Go Slow Attitude

We had to stand at the counter and wait to be served yet there where no other customers at that weighing counter. They completely ignored us for minimum of 20 minutes eventually we get assisted and go to the pay point to wait a further 10 minutes due to not having enough change in the till. Cashier ran continuously back and forth to another till away from the Deli. We asked to speak to the Manager and to no avail. The Cashier had a very Bad Attitude and was on a go slow.
