I really don't tip anyone at the holidays. The trash guys make a bigger mess most of the time than they clean up, the newspaper guy has the gall to put a card in our paper that says, "If you'd like to tip, please make checks out to..." (I won't tip anyone who asks, no matter how politely the request is put), I tip my hair stylist all year long so I don't add any more b/c it's December, and the mail people are an ever revolving cast of nitwits who can't get the correct mail in the correct boxes. It's literally a different person every couple of months.
The only person I might tip is my UPS guy because he really does go out of his way for me at times but when the holidays roll around, he doesn't do my route. I think it's b/c he's good at his job so they put him on the "gotta have it there by 10 AM" route and leave the regular routes to the temps.
