Signing Up For An Exercise Class/Joke

I went to a gym to sign up for an exercise class. I was told to wear lose fitting cloths if I had any; LOSE FITTING CLOTHING: I wouldn't have signed up in the first place If I had some lose fitting clothing; I thought to myself.  Just to give an idea- I am 345 pounds, only 5feet tall. And they had the nerve to ask me to wear lose fitting chothing. Can you believe it, what a foolish world we live in.
