Why does the pizza delivery guy get a tip, but not the UPS guy? How about cabbies? If you are just riding around town without luggage, what do they do that deserves a tip?

I'm generally a good tipper, but I've been in situations where I found out afterwards by horrified family members/friends that I should have tipped someone, but didn't. Once, some guys came and set up a tent in my backyard for a big party we were having. Apparently I was supposed to tip them, but didn't. Oh well, now they think I'm a jerk. I learned my lesson, and then tipped the guys from the nursery who planted a tree we bought. But I didn't tip the other guys who trimmed a tree with a bunch of very high dead branches. I don't think I was supposed to.

It's all so freaking arbitrary. Who starts these customs?
