It's probably beyond our budget for the catering to go over to smart tills all round so the servers don't need basic mental arithmetic or even have to put in the prices. Some places have gone over to cashless systems where you pay with a contactless card. Theatres and the like have schemes where you pre-order your interval drinks. Some line em up on a table and rely on you being honest, I can't see that working at foottie, but having pre-paid vouchers for catering would speed things up on the till at half time. They could be like the print at home e-ticket with a list of stuff and a use one time bar code. They could use the same readers from the turnstiles to check you had paid for your order and aren't trying to use last weeks again.
