I don't use delivery services except for traditional pizza and Chinese food (I tip, please don't hurt me!), but the encroachment of tipping into nearly every point of sale has had a negative effect on the restaurant industry.

Drycleaners? Tip. Movie concessions? Tip. Visiting the farm stand? 3.4% processing fee for cards, plus prompts for tip. Adult film industry? Just the tip. It's outrageous!

Okay, maybe I made that last one up.
