The people who use the "let's divide equally" line alway order twice as much shit as everyone else and expect the rest of the table to subsidize their gluttony. One person once said to the group: "Don't be like old bittys figuring out the splits, let's just divide it equally." That works great with my $15 chicken versus their $40 lobster dish, fucker. Needless to say, I don't do dinner with that person in a group anymore.
The fun part is this person loves to call the waiter boss or chief, quizzes them endlessly about their career objectives, has them running ragged getting water, bread, etc and then tips 15% before the tax. This person always eats out and wants me to go, but I find such behavior embarrassing.
