Mansplaining Comes In All Sizes

I work as a cashier at an automotive retail store. A man comes to the register with a caravan step. I greet him and ask how I can help him.

He puts the box down on the counter and looks me up and down.

Customer: “Do you have any of these in the next size up?”

The box says, “Medium Folding Caravan Step,” so I open my Point of Sale system to check for a large.

Customer: “The next size up is a large, just in case you didn’t know.”

I bite my tongue, hard. I look at him for a second and then nod and continue searching the system. We are actually showing negative stock for the next size up, so he thanks me and leaves the store.

Coworker: “…”

Me: “I never would have known a large is the next size up from a medium if he hadn’t told me.”
