A fine restaurant will often change the mood of the individual that walks in stressed. It is too often the jerk who is serving you does everything possiable to insure you will never come back to the establishment and then expects a 20 percent tip for his effort. Today the kids at McDonalds get more than minimum. I realize in this day and age there are many things to get frazzled about,but, when you enter an eating or drinking establishment you're left to assume that what the customer wants IS to relax a little. Take some of the pressures off for a little while.
Many customers react like spoiled children.
When Schimmel talks about the waiters expecting the customer to change the waiter's mood is irrational thinking. Common courtesy and civility is what's needed. Remember, Schimmel and Bart, Restaurant servers are people,too,not robots. Your animosity shows me that you my want to look into a new vocation. As for expecting the waiter to change a mood, that was not said.
