It common sense, tip off TOTAL bill NOT discounted prices, you got the same service and food so… tip accordingly of TRUE amount. It’s not “misleading” it’s a true fact, tip based of total.
Like I said before, you get $100 worth of drinks with a discount of half off so $50, you do NOT tip off $50. You got $100 worth of drinks and services so tip off that! Don’t like it, don’t go out. Don’t agree, then create a bill and call your govt reps, do not punish fellow humans because you “don’t agree”. We are all just trying to live. If anything, make your own food at home and there you go, NO TIP NEEDED… but no, you came out to get waited on therefore, provide tips accordingly, we are not just at the restaurant for pleasure…
If I was your server, I would get you!! Never would be empty! Usually half full is when I ask if they want another.
