Last year my team and I flew ex ZRH and upon arrival at Kloten I decided to use the Men's room before checking in. My co-workers checked in meanwhile and upon my return I apparantly had the same security agent as they did and when I mentioned that I was working in Zurich and I traveled with my team, she wanted to know why I did not check in with them.
When I responded that I had to use the men's room first, she looked at me and said, "ahh I see well.....okay and she then asked me my reason for work in Zurich."
