When You Have To Go, You Have To Go!

I have just started a transaction for a customer with two full shopping carts. The customer’s kid tells her several times that he has to go to the bathroom.

Me: “Ma’am, you can take him to the bathroom now if you want. It will be a few minutes before I get even halfway through your items.”

Customer: “Oh, no, he is okay. He can hold it.”

Kid: “Mommy, I need to go right now! I have to go so bad, Mommy! I need to go!”

The mother ignores the kid, so he hangs off the side of the cart and starts removing his pants and underwear. I immediately stop scanning the groceries.

Me: “I will not ring any more items until you take your son to the bathroom. Otherwise, I’ll be calling a manager who can handle this, because my courtesy clerk and I will not be cleaning anything up.”
