Clyde, why do you care?
There is only one person who's opinion I worry about that gym. That's the guy that owns the place. The rest of them are paying customers just like me, so they are no better or worse than me, but just ignored.
My gym has 1/2 lb plates but I prefer 1.25 lbs to make 2.5 lb jumps, so I carry a pair in my gym bag. The owner knows and agrees with me. He even said it's on his plan to get some one day, but more racks, bars, and platforms are higher on the purchase list.
I would normally say get another gym, but I think you need to change your focus. Another gym would bring the same problems. The only thing you should care about in the gym is your results. The reset of it is noise.
So get you self a set of micro plates you like, throw them in your gym bag, and get back to work.
