Unfiltered Story #195822

I have a small cut in the middle of my forearm. It isn’t too big, but still noticeable.
Me: (scans items and places them in the bag)
Customer: That cut (gesturing to my arm) is that from shooting up heroine?
Me: (super shocked, but don’t show the customer that) No, its from my dog.
I told my manager who laughed. I am the most innocent looking 19 year old girl who hasn’t even had alcohol, let alone heroine.
