Thanks to all that participated in my public restroom survey! The overwhelming response from you, my beloved friends and family, lets me know that I'm not the only hyperanalytical, OCD one out there. Thank you.
So what were the super-scientific results? I've sifted through the data and this list shows the stalls ranked by popularity (1 being the most preferred):
1. Stall 1
2. Stall 4
3. Stall 6
4. Stall 5
5. Stalls 2 & 3 (a tie)
6. The sink
So after careful analysis, here's my conclusion: Most of my coworkers are either using the first stalls or the last stalls. Or they're using the middle stalls. Or the sink.
Really, that's all I can conclude. So if I really want the peace of mind of having my own bathroom, I'll either need to (a) stop overthinking this issue and just use the restroom like a normal person or (b) start driving home every time I need the security of my own bathroom.
