I work at a small hospital with a shower in the OR locker room. About 3 women actually use the shower: I run to work, another woman bikes to work, and another woman goes to the gym before work. Bike lady starts work at 7 and is often done before me and gym lady arrive. I work at 7:50 but I also do my makeup and meditate so I come early. Gym lady starts work at 7 but usually arrives while I am in the shower.

I take longer in the shower and gym lady is mad about it. If we arrive at the same time I always let gym or bike lady go first. But, if I am already showering, gym lady often calls out to me in the shower to tell me she's waiting and is visibly irritated with me when I come out. She arrives with barely enough time to shower and is sometimes late, so I'm sure waiting for me is very frustrating.

I timed our showers the other day. Both bike and gym lady take about 4.5 to 5 minutes in the stall. I took 9 minutes and 45 seconds. This includes undressing, drying off, and dressing time. However, bike lady and gym lady work in the operating room and are required to wear hats. I work in the recovery room with my hair uncovered. I wash my hair, they do not wash their hair. I do not relax in the shower, the extra 4 minutes is strictly hair related time.

Technically I'm taking twice as long in the shower, but I feel justified in washing my hair, given I don't cover my hair for work. Am I the asshole for taking nearly 10 minutes in a shared shower?
