Input: Let me start by saying I used to be a pizza delivery guy, so I worked for tips and completely understand how it can be. So when I get pizza delivered, or I'm at a restaurant sitting at the table with a waitress/waiter I tip really well. Usuaully at LEAST 25%. 

Having said that, when I get a carry-out order, or the one that annoys me the most, when I go into a regular deli or something and order at the register, I never tip. In fact I actually get annoyed at the second one. I just ordered a sandwich at a deli and there was a tip jar sitting there and the receipt asked for a tip. 

WHY?? 

I worked in retail for countless years and never even remotely asked for a tip. Why the fuck is it somehow OK for it to be different because food? 

TL;DR: Am I the asshole for not tipping when I order food at a damn register, or get carry-out?

never tipping when I order food to go
