The Daddy Of All Turnarounds

Our fast food place asks for your name when taking an order so they can yell it out when your food is ready. One particular customer, a dude in his forties wearing camo, decided to abuse the rule. When asked, he told the cashier his name was ‘Daddy’.
This isn’t good in any situation, but the cashier at the time was a very young girl. I don’t even think she was eighteen, and definitely not his actual daughter.
Naturally, she goes to find the shift lead, Kevin (not his real name). Now, Kevin is a lot of things, and one of those things is gay. I’m trying to find the right words to say this without offending anybody, so I’ll just say he really wasn’t macho.
We live in the Midwest, and I can guarantee he’s been called more than one slur even before actually showing romantic affection toward another guy.
Kevin’s reaction to what the creep was trying to pull was like handing a needle to a kid in a balloon store. When the food’s ready Kevin goes up to the counter and just belts out “Daadddy!” in exactly the tone you’re imagining. Some people go silent, others start whispering, and the entire back is just trying not to laugh.
Daddy doesn’t say a word, just marches up, gets his food, and leaves.
