Tipping the waiters via card?
I do not wish to discuss if tipping is needed and how much you should tip.
I am asking people who work in the restaurant or bar business, especially waiters.
These days it's super popular to have those "add x% tip" options at the card payment terminals.
Now, if I give 10€ cash, I expect that staff will share it, or waiter keeps it, whatever arrangement they have internally.
But what about the digital payments? Do owners take a piece? Taxes? Bank charges? How much of those 10€ would end up in the pockets of workers?
