I played in the gym for three years, not to say that the staff may not be comprehensive.
I don't think there is anything to pay attention to at the front desk, which is different from bars and restaurants. Very comfortable. It's just that members come, you give them the key to the temporary bath and get a card to sell drinks. The front desk of our gym is like home. No one will say anything about your service attitude, and you can't tell who is the front desk and who is the member when you get acquainted.
That is, the things kept by guests must be clearly separated, not confused, not lost registration or something, and not making any mistakes when collecting money. If there is hot water in the club, be diligent and don't break it. Just work hard.
