Got ripped off by a manlet on my subway shift

Im a well respected sandwich artist, almost never have problems. Anyways this kid came in today and I made him a sandwich exactly how he asked, and believe me I know what Im doing the manager says Im her best sandwich artist. Then after he ate half the thing he starts complaining and moaning that I didnt get it right. I noticed a bald spot and felt bad, thought maybe the kid has cancer or something so Im like sure bud its on the house, Ill make you a new one. Then I saw in our mirror that the kid was on his tip toes, trying to look taller and I looked more closely and wait a minute its a balding manlet! I told him hey give it back and he started stuttering saying something about the army and mogging me but his voice was so soft and feminine it was hard to hear. Then he ran out the door. This is bullchit the manager is going to dock this from my pay.
