That reminds me of an incident, there was a popular coworker in my former workplace, he is a devout muslim but was really normal with everyone, he used to hug his female friends and so on...etc.
But he became way worse once he got engaged to a veiled woman (A HOTTIE who was not hajabi! lol)
We were both invited to a coworker wedding; he came with his fiancée; while introducing her to the group (whom are all Christians except me - I am culturally-muslim atheist) he did that 'hand on chest' move while greeting the ladies, she did the same with the men. The group took big offense of the move as they didn't understand it, and me tried to explain them that it was not a hostile move.
It was a disastrous cultural shock...
