The Customer service in general falls 25 points in Quebec, so don't expect much on clear direction from airport personnel, even the Customs officer misdirected us , at an international airport you would expect a little more cordiality. The first officer directed us to go down a line lane towards the security check after having cleared the first security check point and boarding pass and passport check. I know this particular brilliant Madame Customs Officer saw us come from that lane, when we approached her, she asked if were were "connecting flight" in French we clearly were not French speaking since I said no and spoke to her in English that were heading back to USA, but she kept asking and telling us to go to another connecting flights line, but when I insisted we were not "connecting" , I told her the other Customs officer told us to go down this line, then she began speaking in English which I guess made her look like the ass she was, she then said something "I now how to do my job Monsieur", and I looked at her like you could have fooled me!
