It's not an entitlement...if it was it would be included in the bill.
This is a leftover from really cheap restaurant owners. Tell me.............what would it take for you to not leave a 15% tip?
No matter what I order from my pizza guy I give him $5. Sometimes it's a $10 pizza special so he gets 50%. I'm fine with that because I'm too lazy to drive there. :9:
IMO if you don't wanna pay food industry people, stay home.
