Nah, no harm done. Maybe if I was in a bad mood or a big hurry or something. Usually, with 4 racks, there is never a problem anyway. But I can't be using 400-500lbs for olympic squats and give it 100% focus with some fool behind me in the mirror flailing around on a balance board or some dude waiting impatiently to pump up his bis. I just got nice and warm, then had the thing to myself......as retarded as some people are, as a person we're all equal and they pay for their membership just as I do, so 9 times out of 10 I take people in stride.
