Montreal's a big city. I've been to restaurant where I was 100% certain not to meet anybody I knew only to end-up sitting few tables from them. Often I also went to places where I expected to meet my entire family and friends but didn't see anybody I knew. It's the draw of Lady Luck. Each time you go in public, with a lady you don't want to be seen with, you take a chance.
Don't forget, friends of the ones you're hiding from might also see you!
Better don't pay attention and think of an excuse beforehand. Could be a customer? A business associate maybe? Or a friend you haven't seen in a while? Of course, excuses like this are mute if you are all over her when you're spotted.
Be careful!
