Well, remember that this is a different day than what I grew up in, I'm almost 66. Someone around you has a camera with video waiting to put you on YouTube or give to the enforcers of the law and lawyers. Might be embarrassing to have a live video of you getting your arse whipped go viral...My experience is that today, it is quite possible that anyone you deal with is armed in some way.
Unless you feel physically threatened and have no means to escape, you best just let it go, be the bigger guy and move over a few stalls. You can always walk away from the Monkey Dance, but if you choose to stay and kind of taunt the guy, the tables can be turned on you and show you as the problem. Chances are, the individual with the phone videoing the incident did not turn the video on until after the first verbal exchange and only begins with you in his face spewing profanity....That is what a jury will see...Think About It!
