Who reviews fast food restaurants? And who cares? You got ketchup on your hamburger and didn't want that? Boo hoo!! I stop by here once a week for my treat of a double whopper (without ketchup) because no self respecting human being would ever put ketchup on anything.
If they fail, and screw that one task up? I should probably call the manager, leave them a crappy review, sulk and lose some sleep about it, tell my friends what a horrible experience I had and swear off whoppers for a whole month!
If I was really perturbed (and I thought it was really worth the time and extra effort to complain) I could probably get some free stuff in exchange for my phone number, address, and email?
But I eat it anyway, grin and bear it and tell myself maybe ketchup isn't so bad after all...
(For the record, they get it right 9/10 here in my experience.)
