Planet Shitness is a doozy, sure enough.  I trained at one for awhile because they were the only game in town and I couldn't afford the space and equipment to build a good home gym.
I left after I brought a dip belt from home to do weighted dips and chins there.  For a time, nobody gave me any shit; then, one day, just after finishing my dips, some nimrod employee came over and asked me, "Sir, is that a dip belt?"
I had just topped out at a working set of my fat 235 pound ass plus a mighty 180 in plates for a DC style rest-pause sequence of 15, 7 and 4*****, so I had no clever response -- too tired, you see.  So, I simply said, "Yeah," and he told me the belts weren't allowed because "they are too much like powerliftin'."
*****I tease.  I never did more than three plates for eight, I think.  But the kid really did say that.  And I did have the wherewithal to ask him if I could still bench press.  "Duh, yeah," he said, clearly confused.  I told him to look up "powerlifting" on his computer, walked off, finished my workout and joined a Gold's in nearby Charlotte a week later.  The commute limited me to only two gym visits/week, but I always thrived on lower volume HIT stuff so it was cool.
