Telephones are a wonderful invention. They have worked quite well for a number of years now. Friends calling you on their cell phone from the freeway. I've never had a call where we didn't get disconnected. Loud music in the gym.
Background music is suppose to be in the background.
People who use more than one dot in a filename on Unix machines. Sales clerks at electronics stores asking for your phone number to put into their cash register when you try to buy something. Sales clerks who ask for your zipcode to put into their cash register. You get a discount on one or two items, they keep track of everything you buy so that they can target advertising better. Nice little software companies, who use to have decent customer service, selling out to big corporations, and now you can never get the answers you need.
