They delivered my sandwich without a key ingredient (and without asking if that was okay). When I bit into it, the tomatoes were so clearly bad that it made my stomach turn. Even after I removed them I couldn't eat it, because the bad tomato juice had gotten on everything.
UPDATE: I was starving after the gym, so I caved and tried them again. What a mistake! They forgot an item, didn't include a straw for my drink or napkins, took 37 minutes (not by any means "freaky fast"), and didn't have a pen for me to sign, but insisted on awkwardly waiting in my doorway while I searched for a pen. No thanks. Not again.
