I think most of us go with the flow when we're in other countries. We don't want trouble with the law, understand the cultural differences, etc.
I got my crotch pat down in FRA by a security official with happy hands. Didn't like it, but I didn't cause a ruckus or complain either.
Most understand that we're guests in the particular country were visiting.
However, that doesn't mean we're going to stand for it in our own countries.
