Meh, that's not too bad. I usually wait that long when I go in to fast food places anyways. Plus if you're inside getting food, you can see when there's a single person vs a whole crewNot really. I was in the middle of working on an order and the person who came through the drive thru left before I could take their order because I took too long.
2 people waited almost 10 minutes for their food because I was by myself.
