Tips used to be reserved for those that actually had to live off tips, and the law allowed the employers to pay them less because tips were expected to help them supplement the low wage. Now it seems everybody wants tips even when they are paid regular wages. I'm a generous person, but it kind of bugs me to see tip jars and people expecting tips that actually get paid a real hourly wage or salary, not the 2 or 3 bucks that servers get paid.
