That's my preferred one.
> 1. Point of sale system that explicitly prompts for a tip.
Seemingly the same general idea, but also for...
Buying things, as opposed to eating/drinking? (I've seen some at what was arguably grocery stores that also had some sit-down dining, paid on the same terminal.)
Bars that already include a 20% service charge, and the prompt says 26%/28%/30% on top of the service charge? (Fortunately, I've only seen that one once, so far.)
> 3. Check to sign with a tip line.
These can be confusing at takeout places!
Only very recently, after settling on leaving a "compromise tip" between nothing and a sit-down rate (and feeling appropriately mediocre about it) at a local takeout place, I ordered with the owner for the first time – and he immediately threw away the receipt as it came out of the machine with a smile, not giving me a chance to fill the tip line. Apparently no take-out tips expected!
