"Hey, my 3-year-old needs to use the bathroom. I'm going to buy him a donut, but he really needs to go," I say, waiting at the end of the line. "No, he can't go until you buy something," says the rude server. "He needs to go; I'm going to buy a donut. Please let us use the bathroom first." "No, he has to buy a donut." I wait. I buy a donut. "You can use the bathroom now," she says. "It doesn't matter," I say. "My son peed himself. Thank you very much."
