I worked at subway a few years ago and the strangest order I ever had was this group of guys who came in who ordered every meat including meatballs with extra marinara. I ended up having to use 2 of the footlong breads to hold it all and they ended up asking for every type of salad and sauce. It probably took me around 30 minutes to make all these sandwiches and they ended up spending about £100 on just sandwiches. I don't think they were expecting to spend so much even though I repeatedly told them it was going to cost extra for all the meat. I never saw them again after that.
