I've had beers with Afghans. I shared a few beers with a mujahideen general who later became briefly a Taliban representative in Europe.Sooo no beer with the Afghanis I gues.
BTW, a pet peeve of mine: an Afghani is a unit of money. A person from Afghanistan is an Afghan. It would be like saying "Jestem Polski" instead of "Polakiem". Understandable, but not technically accurate.
