I'm a customer as well but have been there enough times to know there is a security system. I believe they take consignment and am guessing they have "booths" though I've never seen anyone except at the POS and occasionally in an area near a canteen of sorts.
I'm just a customer there. Sorry. You would have to call them to get your answers, even if they rent booths etc. It doesn't mean any are available. Good Luck
