Response to the "buddy pat" from AMOG. In church of all places.

Particularly interested in responses from people who like or have used amused mastery, thanks:

Maintained amused mastery very well in the face of AMOG verbal shit. Rolled my eyes at his expense, and the girl did the same back to me. He did not break our frame. Fyi this is happening in a church with lots of people coming in and out around us. But as he walked away, he put his hand on my shoulder and patted me and made a little laugh and winked at the girl.

Now in this situation, how would you respond to the physical pat?

i'm playing it cool in amused mastery and he pulls a physical contact on me. And in fucking church. I maintained amused mastery but I wondered if used mastery is not enough when someone touches you like that.
