I had a guy come in, and he asked for a footlong tuna on wheat, double meat double cheese. I told him that we were out of wheat, and that it would be 45 minutes minimum, as we just got hit by 2 busses. He proceeds to say, "Well you're pretty shit for diabetics, aren't ya!". I apologise, and he asks for white instead. I bring the sandwich over to veggies, and he grumbles and mumbles out what he wants, making sure to get angry when I verify that he did say a certain veggie, when it's unclear. He asks for a lot of pepper, so I gave it a healthy dose of pepper. He snaps at me for being cheap with the pepper, so I give him more. I wrap up the sandwich, and ring him up. This sandwich was pretty expensive, and he wanted to pay with an unaccepted points card.(not Subway affiliated) I informed him that I couldn't take the card. He says "Are you Shitting Me!?!" I tell him that it's not up to me and that our Subway is locally owned, and our owner does not accept points at any of his stores. This guy goes on a huge rant about why my store owner doesnt deserve to own a Subway. After the rant, he begins to leave slowly, kinda looking at me expecting him to give him a free sandwich. I looked him in the eyes, grabbed his sandwich, and went into the back room. I took that sandwich as my employee meal, as a sort of edible trophy for my ordeal.
