The door opens up and I see two people walk in. One is very, VERY short. No bigger than my ten year old niece who doesn't even come up to my boobs and I'm only 5'5'. I'm very used to people trying to bring their kids in here with them, so I instantly call out "You can't have your kid in here with you, I'm sorry!" because hey, knee-jerk reaction because people try to bring their kids in here ALL THE TIME.
Bad idea, apparently. It was just a very short nineteen year old girl with her mother. Fuck.
I feel really shitty now, but I could have explained all of that to her had she stayed in the store instead of spitting on my pipes display and storming out.
