I'm not so sure this was unscheduled. Would both owners be at a Dunkin' Donuts in suits??? If they were working, I doubt they'd be in suits. If they weren't working, and came in to see the Prez, then suits make sense.
Or am I thinking about this too much?
What I think is more likely it was not on the printed schedule for security reasons I am sure the manager of the store knew and I expect he just told his staff to dress smartly as a VIP was visiting.
Re the owners though maybe they do dress in suits I would expect the local Macdonald manager in Ashford to wear one.
I'm with you. Maybe we need a definition of "unscheduled."
