Tim Hortons food chain

I'm at the Calgary airport and we're eating at the Tim Horton in the secure area in the US destination wing. They have a very limited selection of food and very curt staff at this outlet. I could have any type of bagel that i like as long as it is sun dried roach with cracked beetle shell flavour. I try to visualize how this outlet fits into the pecking order at the airport and I imagine that the Tim's in the front area of the terminal gets first dibs at the food delivery from the Tim's truck. Then the domestic wing gets the cast offs. The US wing staff probably have to dumpster dive the rejects and wipe off the dirt to stock their shelves. Which would explain why my chocolate glazed donut had very little glaze on it.
