Earlier quoted context omitted.
Delivery used to be free from most pizza places and the occasional other restaurant that delivered. Now, almost everyone charges a delivery fee. The idea of tipping on top of that just irks me to no end, although I do it so they won't spit on my food next time. I don't tip my Fedex or UPS deliveryman, why should I tip for food delivery when I've already been charged extra for that exact service?
There are people who tip the fedex or ups courier? I didn’t even consider this was a possibility.
From a foreign perspective, where I don't think I've ever tipped anyone in my life, it's absolutely bizarre.
