Will people look at me crazy if I come straight from work to the gym?

Im a cna and im gonna work overnight tonigh. My gym is literally on the same block as my job, so instead of going home & changing I was gonna go straight to the gym, change there & workout. Will the people at the gym think it's unsanitary. I mean it's not like a gym isn't dirty anyways. All of that sweat.
