General Discussion

The act of tipping itself is a cultural thing it needs to be addressed culturally. If you can’t tip someone for something, complications in the law arise that may disallow giving money to people in general. For example how do you distinguish between tipping a server for a meal and giving the server a dollar as a gift?

If you are a customer at a food or retail business and opt to give one worker there a cash gift while they are on the clock, how can that not be a tip? Current US laws like FLSA already have a very clear definition of tipped wages which would include anything matching that description.

Even if you want to allow that sort of cash "gift", eliminating tips for credit card payments should be enough to shift the norms and expectations. Namely, prohibit payment terminals from prompting for a tip as part of the same credit card transaction and prohibit the tip lines on receipts. Majority of Americans don't pay with cash. If a business says they accept credit card, customers clearly aren't expected to give a decent tip and by extension the advertised meal prices and wage amounts should reflect what the customer is expected to pay and what the staff should expect to earn independent of customer whims.
