if you go with something other than myas, prepare to replace some hookahs in your business, plain and simple. i'd suggest putting a couple cameras up. if you don't feel like going professional with security you can buy personal security cameras that run via usb or something that connects to a tv to record like this:
alright i'm getting nerdy. sorry i'm in networks class :P
anyway, our local hookah bar started out with myas, and then moved to generic Egyptians, but he is starting to phase out his Egyptians with more myas again.
