Carriage Hound

There's this one employee who works here named Timmy and he has very red hair and he's the nicest kid. He was bagging on register 14. Gregory came in from outside and went up to the assistant manager that night, Aiden to see what he was supposed to be doing. She said to him, "Send carrot top outside."
He heard, "Send carriage hound outside."
"Who's carriage hound?" he asked seriously.
"No! carrot top!" Aiden said laughing. Gregory went to pass on the vest and switch places with Timmy.
Later that night Gregory told me what happened and i thought it was the funniest thing ever. We kept laughing about it. Every time Gregory would come in to put away the carriages he had gotten Gregory would call him carriage hound. Timmy would smile in puzzlement and we would just crack up. After the first time he stopped asking why we were calling him carriage hound. He probably thought we were complimenting his carriage-getting skills.
Since we were on register one, we could see all the customers coming in and this one red headed kid came in. I looked at Gregory and we both laughed.
