Why should you tip?
Haha, it's clear that we've grown up in very different places. Does everyone you know sit on a high horse? I totally agree with the whole "if you can afford the restaurant, you can afford the tip" thing though. That's why I think it's rude. But it's even more rude to tell people what to do with their own money, and to judge them when they don't do the same as you. It's worse than those annoying charity morons, who tell you you're murdering African children because you don't give £1 a month to charity.
