Even during Covid, I would say most of the time the line is reasonable and moves okay.
Timmy’s often has longer lines but they move fast. If it looks too long I would just go inside or think twice about their modest offerings.
The Harvey’s restaurants here are quite clean; can’t think of one that isn’t.
Once recently at a hamburger place I was asked to pull up and wait. Took ten minutes for a very typical order, but was hot and freshly cooked. Atypical, so nothing to really complain about. Likely due to staffing.
Occasionally a fast food place will give you large amounts of bad food. I remember going to an A&W and they seemed to be trying to unload their stash of cold food. Got three times the usual amount of onion rings. Cold, they were barely worth eating. Does this happen to other people? (Tims’ has often been generous with extra food at end of days, I’m talking large amounts of sub-par stuff.)
