BOA is one of the best agencies in BC imho-- a no brainer over the minefileld of sketch and scams that is Leolist these days. No privacy concerns at all for me. If I were you I would park on the street by the car shop and then walk down the alley through the liquor store parking lot until you're there. 9/10 times you won't see anyone and if you do it's two ships passing in the night sort of thing.. I've never bumped into another client there. Privacy is actually a step up from most places as you walk right into the room and only interact with the girl during the whole of your visit.
Who are you seeing? A lot of great ladies there

Good luck and have fun.
