It’s not quite what I meant but I suppose they can. I just meant they often don’t know other clients are until they meet them. That’s why they ask that you show up clean, not be rude etc.Plus if you read between the lines of JRPlumber’s reply, SPs can choose who they see especially the good lookin fellas. That makes sense to me. It's always better to find an SP who enjoys your company or at least pretends too. Try Toronto more options and better service compared to Ottawa.
