If they show up with an entourage, turn around and go back inside ...
ONE man should know what he's talkin' about .... JUST LIKE YOU
Don't fall for the gang up ... even if they stay in their car or away from you on the curb
Mano a mano
If CAIR shows up with a posse of bearded glowering muzzies, the shop owner should phone the PD & ask for a police presence equally large. Or a counterposse of Oath Keepers. Or bikers.
As for their demand that “you must let us teach you about Islam!”, tell them to pork off!
D@mn it, this is less than 1% of the population dictating to the rest of us!
