Or WIBU, rather.
It's a gym instructor.
Ordinarily, the gym instructors hang around in the office attached to the gym (with the doors open) or walk around cleaning the equipment. This guy however, hangs around empty equipment staring at women people or hanging around their machines making small talk. He doesn't seem to be offering any advice or encouragement to those he leers at speaks to and they don't seem to respond much to him.
The next bit would form the main part of my complaint:
I went a few days ago and he was sat side saddle on one of the spin bikes chatting to a woman (who was chatting back, texting and 'spinning' at a snails pace). I like to incorporate the bikes in to my workout but as there are only two, I was unable to.
I usually end up leaving the gym early because I just find it so uncomfortable when he's there and unfortunately there are no other gyms nearby or really any other times I could visit.
Would I be unreasonable to make a(n anonymous) complaint about his conduct?
