That’s exactly what I said, though: if you don’t want to tip, don’t go to a table service restaurant. There are plenty of restaurants where tipping is not expected, feel free to go there and not give a shit. Most restaurants offer take out now too, so you can still eat your favorite meals.
You are contorting yourself to justify the discount you give yourself at the expense of the person waiting on you. You are taking advantage of the fact that tipping happens after service, and that it’s not legally enforced, to lavish in the benefits of a personal slave without paying them for the pleasure.
You know very well that tips are expected, and know very well that the quality of the service you receive reflects that fact, and know very well that if you were honest up front about your beliefs on the practice, that the service you received would not be up to the quality you feel entitled to. Rather than reflect upon the unpleasant implications thereof, or accept service in line with the compensation you provide (instead of the “personal slave” you’ve become so accustomed to), you’ve decided to remain entitled.
You know very well that you’re exploiting some poor worker via unspoken convention, and yes you should be very, very ashamed.
