This is more like a preemptive AITA. Some background: I am a member of a 24hour gym chain, and I have been a member of this branch for nearly 2 years since it opened. At this gym, it is always busiest at around 6-9pm weekdays and particularly on Mondays. The gym has 2 elliptical machines and 5 treadmills.

Today (Monday evening around 7:30pm), all the elliptical machines and treadmills were occupied. I notice that one of the staff (the head of the trainers) was on the treadmill. A lot of people were just waiting around for an empty machine and this staff member was on this machine for more than an hour while looking at her phone and seeming like she was on a leisurely stroll a lot of the time. This is the first time I have noticed this happen. I know staff members can use the facilities because I see the trainers use them, but mostly during the late off-peak hours.

Would I be an entitled asshole if I said something/complain if it happens again? Looking for opinions whether I am correct in my thinking or I’m just plain wrong.
