finally a station somewhat in my area carries bulk DEF, so I am excited and drive a little out of my way to get some. I get there swipe my CC at the pump, pumps some then clicks off, I am talking only a very small amount. finally I phone the cashier and they inform me I have to buy this stupid adapter with a magnet in it. it costs me $15 bucks.

she said its to prevent some idiot from filling their fuel tank with DEF. if your stupid enough to do that you get what you deserve I say. anyone else seen this??
