I should have guessed that might happen cause they were having trouble keeping the sandwiches in order as I went through the line. Sandwiches were coming out of the toaster and going in front of me, then they'd change them around. When I got to the cash register to pay someone handed me a bag and there was confusion with another person in line, my change and my rewards card so I didn't think to check the sandwich. Come to think of it, I didn't count my change. Hope that was right!
P.S. Just checked. At least I got the right change.
