Most spas have CCTV cameras covering the front parking lot and can see clearly what's going on. And lots of spas have back doors as well. Bylaw don't have enough man power to sit whole day at the front and watching who's going in and out. It can happen only if you have pissed off Bylaw officers some how somewhere. Most of the Bylaw officers are nice and friendly people just doing their jobs. If you're nice and polite with them, show them respect, they won't come after you. If you're rude to them, show no respect, they will come after you no matter where you move.
