Nearly every fast food place in the UK has gone to self serve machines because of that, and taken away the ability to even take orders at the registers.

Although in practice it now means a bunch of staff helping old people use the self serve, rather than just taking the orders.

I very rarely even go there. The food isn’t even fast. It seems mostly cooked to order because it’s cheaper to waste my time than it is to give away a handful of old burgers at the end of the day.
