I smell horses

I work at a restaurant and aside from the smell of tomato sauce and melty cheese, I smell horse. It’s faint but distinctly horse that I smell, a mixture of hay and droppings can’t find the source and it comes in wafts when I give up looking. Apparently im the only one who smells it. Im asking around but it’s unlikely any of my coworkers own horses, just not that kind of crowd.

update: its been a minute, still smell horses at work. i don't like closing by myself, they turn the lights off on me and i trip into stuff, i just blame the mess on front. hate the feeling of being watched though, always one room away.
