In my area (upstate NY) It's been common practice for some time to have percentage-for-tip options when paying in restaurants, but, so far, I have not had any gratuities pre-added into the checks.
I did have a situation with ShopRite. When ordering online there are different options for tipping the delivery person, which I thought was a nice convenience in that it meant that I did not always have to have cash upon delivery. Then one of the delivery persons told me that when that option is selected on ordering, the tip is included in the delivery persons pay and taxed. That being the case I have resumed tipping the delivery person with cash. 🫤
