I’ve been to a number of venues (including Abbey Cinema in Abingdon) that uses a fairly basic app to order drinks on that are then delivered to the table/seat.
Could a Farrs app not be developed where people could order their drinks before/during the match which are then prepared a few mins before half time etc.
It avoids the need for printing/exchanging vouchers or tokens and should only require your staff cross referencing the order on your system with the order on someone’s phone.
Wetherspoons have done a fairly similar thing to reduce queuing at the bar etc. There’s not a huge amount of variety in terms of alcohol options at the moment so it could be trialled with that.
