(I’m an employee stocking the shelf at one end of an aisle. A customer enters at the far end by the milk and is coughing constantly.)

Customer: *coughs*

(I briefly glance over. She’s staring at the milk.)

Customer: *coughs again*

(There’s a long pause. She’s still staring at the milk.)

Customer: *loud coughing*

(I turn to see if she is covering her mouth, but instead see her charging down the aisle at me.)

Customer: “What is wrong with you?! I’ve been coughing to get your attention down there for five minutes! ”

Me: “Ma’am, I glanced over at you several times. You never looked at me.”

Customer: “Oh, yes I did! What does a person have to do here, fall on the floor and have a seizure to get some milk?!”
