QatariLady - I would tend to agree with the guidelines you outlined, but others on QL (and in other places) say that all of that is a no-no. Hence the confusion.

If it was written down officially somewhere then we'd all know what was right and what was wrong. That's the point I'm trying to make. As it stands, they can arrest you for any form of PDA, because there's no law specifying the limits.
