Pharmacy across the street. At least one of the pharm techs knows me be name and I think her memory is aided by "that guy with the gun." Or maybe I come in so often for meds.
Sportsmans Warehouse. I think their gunpowder is more expensive than Scheels but Scheels is in a gun-unfriendly development so I take my business across town. Not this time, but a previous time I OCed into S.W. and bought powder, the guy behind the counter thanked me for OCing.
