Rude service

We stopped at 9:20pm at KFC Waterstone to order some food after our kids school prizegiving. They informed us that they will Only start serving at 9:30 pm which we were happy with. So we waited, then another realy rude attendant open the window at the window and told us to keavs. We explained that we are willing to wait the few minutes, but he tomd ys to leavd bevause the “time” is running. He was exceptionally rude! We eventually left after he refused to serve us abd went to Macdonalds
