I ordered a Jr. Burger with ketchup only, plus onions. Not hard. But for some reason, it took forever to come out. When I unwrapped it, it was obvious that this had been a burger that was made a long time ago, with stuff scraped off it. It was (a) stone cold, (b) had traces of mustard on the bottom of the burger, and (c) there were weird smears of mustard all over the wrapper (did they scrape it off *with* the wrapper???).
Not an earthshaking suck, but come on - you just don't do that.
