Kayakas!

You’d think that everyone would be happy if given the thumbs up sign.  For us, this common gesture means approval.  For others, however, it means something else.

In the Middle East, it can be roughly translated as “up yours!”  That would definitely get you in trouble, should you decide to give, say, that vendor you are bargaining with, a thumbs up to approve of the price.

You might want to keep that in mind for your next trip.
