I’ve just remembered a story about one of my old co-workers I wanted to disgust you with.
I used to work in a large department of about 14 people, processing payroll. We often suffered from paper cuts, loose/painful cuticles, broken nails, splinters, etc. so I kept tweezers and nail clippers in my drawer just in case.
One day my coworker asked me to borrow the nail clippers. As I was stepping away from my desk I just said ‘sure, they’re in the top drawer’ and began to walk away. What she did next horrified me. She plonked herself in my chair and took the clippers out of the drawer. She then kicked off her shoes, plonked her feet on my desk, and began cutting, cleaning and filing her toenails. When she was done I told her to keep the clippers and cleaned my entire desk with industrial-strength disinfectant. How gross can you get? 0528-10
I had clear mental images of a scene from “Star Trek Enterprise” where Dr. Phlox is cutting his lengthy toe nails using a small cutting saw. If I could have found a Youtube video of the scene, I would have posted it.
In situations like this, it is perfectly acceptable to express dismay while the activity is in progress. Stop all movement and looking at the cow-irker with a slack jaw and wide eyes say, “What are you doing? Kindly do that on your desk.”
