A simple GTFO by one man perhaps would have been appropriate. Is that a bridge too far out of a dozen males?

The best possible response is to ignore them and continue with your meal as though they weren't there.

Otherwise, you are just falling for their race-baiting trap. They were no doubt hoping some "cowboy" would step up and make a scene so they could Twitter it around the world and fuel the flames of racial warfare.

Trust, me indifference is the prudent approach here.
