I'm a school bus driver and we get tipped (at Christmas and the end of the year). It's fucking ridiculous. One of my coworkers last year even handed out tip envelopes to the kids - and got suspended for it, fortunately. Imagine being a parent and seeing that bullshit when your kid brings it home.

I don't throw away the gift cards, of course, but it genuinely means a lot more to me when I get a hand-written card from one of my kids (especially if it's not accompanying money).
