Input: Consider Input: I dread many things about dining out in the coming year  from closings of beloved restaurants to ever-weirder ramen mutations. But the scariest of all may be the expansion of the online reservation app Tock  which makes you pay in advance for your meal at the time of booking — mostly at super-luxury eateries  but increasingly at lower-priced places  too.
The great Eleven Madison Park is the only place in Manhattan that currently uses three-year-old Tock for all seatings (though it’s also one of the very few restaurants worth such hassle). In Williamsburg  tiny Aska also uses the app exclusively. Now  Tock — which is used by just 300 US restaurants  compared to 43 000 for OpenTable and 1 000 for Resy — is trying to lure in lesser joints such as Té with Tock Intro.
Backed by millions of dollars in venture-capital funding  Tock promises great things to owners. Its platform can help them better manage reservations and reduce no-shows. Customers supposedly benefit from avoiding the hassles of reserving by phone.
But I hate having to buy a ticket for a meal — even for a world-class place such as Eleven Madison Park or Chicago’s Alinea  which is co-owned by Nick Kokonas  who also happens to be the founder of Tock.
Certain places that use OpenTable or Resy require a $50-a-head credit-card deposit. I’m not crazy about that  but at least we’re not giving them an interest-free loan of nearly $1 200  as a table for four would be at Eleven Madison Park reserved months from now on Tock.
Tock is striving to make inroads here by handling New Year’s Eve bookings at places that would otherwise use OpenTable or Resy. “New Year’s Eve has notoriously high demand and no-show rates  so we’re seeing a large number of restaurants using Tock Intro to combat the no-show issue ” says a company rep.
Among them: The Lambs Club and Lupa Osteria Romana — where you can only book the $275-per-head “Roman feast” starting at 9:45 p.m. on Dec. 31 using  Tock .
 Tock ’s strategy is to persuade users of the limited service to switch to the site full-time.  Tock ’s rep says  “Many restaurants start with  Tock  by offering a single prepaid experience  which is what you’re seeing with Lupa’s NYE dinner. After they see the full platform … they often transition all reservations over to  Tock .”

Input: Consider Input: After enduring one too many maddeningly slow boarding experiences  Jason Steffen a professor of physics and astronomy at the University of Nevada Las Vegas  began digging into the unexpectedly complicated mechanics of efficiently ushering passengers onto planes.
In 2008   Steffen  created a computer simulation to evaluate existing boarding methods and ultimately design what  he  claims is the most efficient option for getting restless passengers into their seats. The results were published several years ago in the Journal of Air Transport Management (summarized here).
In  his  research   Steffen  identified the two most common factors responsible for slowing the boarding process to a painful crawl:
In fact  the most routine boarding process â from back to front â is actually the slowest of them all   Steffen âs argues  Itâs even less efficient than boarding a plane in a completely random order.
 Steffen  claims that  his  proposed method  which minimizes the former issue and eliminates the latter  could significantly reduce boarding times  thus cutting down on overall door-to-door flight lengths  and ultimately saving airlines hundreds of millions of dollars a year.

Input: Consider Input: Sen. Luther Strange (R-Ala.) introduced President Trump at a campaign rally in Huntsville  Ala.  on Friday night. (Marvin Gentry/Reuters)
The Republican primary in Alabama's Senate race is a proxy battle between political outsiders  who largely support challenger Roy Moore  and the GOP establishment  which backs  incumbent Sen. Luther Strange . But  Strange  on Saturday declined to give a vote of confidence to the face of his establishment base  Senate Majority Leader Mitch McConnell (R-Ky.).
Appearing on Fox News the morning after a campaign rally headlined by President Trump   Strange  was asked whether  he  will support McConnell's continuation as majority leader if the party's latest effort to repeal the Affordable Care Act fails.
 Strange  seemed uncomfortable and stumbled through a noncommittal answer.
 Strange 's equivocation underscores his difficult position in the race. Despite having Trump in his corner  he has effectively been cast by Moore as an establishment figure who will perpetuate Washington dysfunction. Moore has seized the outsider's mantle for himself by highlighting the rebellious streak he displayed as Alabama's chief justice  a position from which he was removed â twice â for defying judicial orders.
To claw back some credibility as a politician who will âdrain the swamp â  Strange  cannot appear too closely connected to GOP leadership.
And yet  Strange  is relying on McConnell for financial support. The nonpartisan Center for Responsive Politics reported Thursday that as of early September  the Senate Leadership Fund super PAC  which is affiliated with McConnell  had spent $733 000 to promote  Strange  and another $2.5 million to air negative ads against Moore.
Since Sept. 11  the Senate Leadership Fund has spent more than $720 000 on postage and printing to advance  Strange 's cause and oppose Moore  according to the Center for Responsive Politics.
