Same here. I always tried to give them the benefit of the doubt, especially since I used to be a lard guzzler.  But every time, the fat fucks just put in some half-assed effort that makes me roll my eyes so hard they strain, then get this cocky look on their faces and even give me condescending looks when I start my first sets with light weights to warm up and work on my form. Then they don't clean after themselves, and they just get in my fucking way when I'm trying to follow my routine.  Now I just hate.
