One of my gym peeves are. Like when I am at gym and see people not wearing the right foot where. Like sandles for example. Do think how dumb can one get.
I always enjoy the girls and guys who look like they are made up for a night on the town, wearing a perfect set of work out clothes and facetiming while "working out". The only gyms I will work out at have a no cell phone policy. They allow it for music but if you take a call on the workout floor, they will ask you to leave.
