Just learned that a friend of mine always tips 10% on takeout. Ive never tipped on takeout unless they offered me a water/soda while I waited or something.
US biased, but I’m a little curious about other countries as well.
There's a donut place I go to that hands you a device/keypad thing when you pay and it has like a gazillion prompts and questions, including tip. But I found that if you order ahead and pay online, you can skip all that and just pop in and pick up your order. So that's what I always do now.
For anyone in the Chicago area, you need to try Stan's Donuts. Everything is good but specifically the yeast-raised donuts are to die for. Best Boston Cream donut I've ever had.
I just assume that the tipping screen is built into the POS (cash register) software. It doesn't know if this is a tip appropriate business, so it just asks for one.
They surely wouldn't complain if you did, but I don't think that any of those places are trying to manipulate people into tipping through their cash out screen prompts.
As a business owner that has used several different POS systems, I can tell you that they are choosing to have you see the tip prompt. I have never seen a system that didn't have tipping as an option that can be turned on or off. However, it is usually set to on as default.
