I'm pretty, if not absolutely, certain that you should not be using the building gym intended for employees of office renters. I put up with the son of the main cleaning lady, other cleaning people who use the machines as lounge chairs, but this is getting really ridiculous and I'm going to be entirely peeved if I go down there one day and my machine (the only elliptical) is taken by someone WHO SHOULD NOT BE THERE. Isn't that considered stealing? Also, Dear Mexican lady in her late 40s, wear a f*cking sports bra and a shirt you can't see through if you're going to jog (poorly, I might add).
