I think it is the business owners responsibility to pay fairly and make the price the actual price, not throw on fees and tip requests during the final transaction. I know it's not the employees fault especially on POS.

Even people that I normally and happily tip (beyond servers - say a taxi/Uber) I'd just as soon be charged appropriately as to have a tip request at the end.

But I think in the spirit of the thread it's that these POS systems now make it to easy to misrepresent prices - at one point another local place was adding an "inflation charge" and a "healthcare for employees" and a "service fee" for pickup orders (presumably because people don't tip pickup but the system asked for a tip anyway). Just tell me the price and let me decide don't spread the ticketmaster model everywhere.
