Kids these days...

Just left the Mac store, walked in and asked kelvin for a 12 volt charger for an iPhone 5. Kelvin says ok but starts to blush. Kelvin walks me towards the chargers and says ok what was it you needed, 12 volt charger for an iPhone 5 I say. Kelvin damn near freezes up, looks like a squirrel scared to cross the road, finally he says "so you want one for the wall or your car?" I start laughing and he says "sorry I don't know what a volt is"
