Stop in for a cup of coffee

What was your answer??
So I was at the local Kroger grocery shopping. Get to the register, there’s a 40ish year old woman bagging the groceries, girl in her twenties ringing everything up. Cashier girl asks me if I want them to put my milk in a bag, told her, that no I’d like the milk left in the jugs. She doesn’t even catch on, turns to the older gal bagging, tells her, no bags, he just wants the jugs. Older gal just Looks down at the milk, pulls her apron out a little, looks down, then looks up, stares at me and just bursts out laughing her *** off. Cashier girl has no clue what’s so funny, it took me about 5 seconds to realize what had happened and why it was so damn funny. Bagger gal tried to explain it, young girl still wasn’t getting it. Finally it clicked and she turned about 7 shades of purple.
