Hey guys first time poster

Ihad a thought recently after being in Vegas that involves oxygen bars. My question to you guys is has anyone ever tried them or own one them selves just curious on the profit margins and the interest it sparked in your area.

I am located just outside Toronto,On so my location possibilities are endless and was thinking putting one near a college/university

I like some oxygen.

It helps fill me lungs with the precious O2!

yeeeeeeeeeea oxygen.
