It's safe to say Subway is serving up some of the most sub-par sandwiches in America, but there's one thing you can say about them, and indeed most chain restaurants- they're consistent.
People know what's on the menu and they expect it to be available and ready for consumption when they arrive, but do you know what happens when those expectations are diced like an onion?
Customers get all crusty, like the lady in this video who was deeply hurt by Subway's lack of meatball subs. (NSFW due to language)
