That’s my point. This restaurant is try to bait and switch their customers by giving a misleading food price and adding a service charge. It is like a cell phone company adding garbage fees.
As for my initial comment - if you add a percentage for service, that ends my obligation to tip.
I’ll just add that BBY and Michael’s business mode is to use the Anchoring effect year round, so they can constantly offer 40-60% “discounts”. If you paid full price for anything at those stores (BBY is out of business, but still) you got ripped off.
