The best restaurants serving American food in Montrose and District Angus Central Scotland

Went into collect my order, so stood to the side as it was being made. As I was waiting, around 6 young teenage boys came into the shop. Some went behind the counter into the kitchen, and some sat on the window ledge bit. One boy began reading the orders that had been printed out, not sure if he worked there too or was just being nosey? They were loud, going in and out from behind the counter (without masks). They weren’t customers, they just came in for a chit chat and then left. The boys left then straight after my order was brought out to me - I don’t know if I had my desert made by a worker or a random boy. Usually like oh fudge as their deserts are good, but their service isn’t.
