This is bonkers. Just include it in the price… I would definitely refuse it and have done it one time, when it was not clearly stated in the menu that service will be added. The waiter claimed it is “a standard fee”. No, it’s not and should never be.
I’m afraid that as long as you have to go to github and run such scripts for these things, Lemmy will stay a nerd-only place.
Great, looking forward to hear your feedback!
