Orange shirt
Back in my college days I worked at a local sandwich shop, Blimpie. Our uniforms were polo shirts that were either mustard yellow or orange, with ‘Blimpie’ embroidered on the upper left side and we wore visor hats. I had found some official bucket hats on ebay and wore those.
One day I had to get something for work at Home Depot. That day I was wearing the orange shirt with orange bucket hat. I did not have my black apron on, which probably would have given me away as not working there, but as I was scanning a shelf for the item I needed, an HD customer approached me and asked if I could tell him where something was.
I turned and looked at his list, up at him, then honestly answered “nope! Sorry” and turned my attention back to scanning the shelf. The guy stood next to me for a few seconds with a scowl on his face so ignored him. He wandered over to an actual HD employee down the aisle and instead of asking his question, angrily pointed back at me and said loud enough for me to hear “your coworker was very unhelpful and rude. You should write him up!”
The HD employee apologized and approached me and opened his mouth to speak when I turned toward him and asked where my item was. He stopped, looked at me, then at my shirt, and stammered that my item was on some other aisle. I said “sweet. Thanks!” Then turned toward the other guy and smirked as I passed him. The HD employee caught up and as I left the aisle, I heard him say to the guy “he doesn’t work here.”
