How many of you have got the "Propylene Glycol?! That's antifreeze!" line before? My response is to give them a blank stare, like the one you get at the post office counter, while I tell them to Fu(& off and die quietly in my head.
Jip a couple have tried to tell us that one. Luckily I have JACO... the chemical engineer... explaining to them the chemical component difference in Propylene Glycol and antifreeze, as on that chard he loves so much.
Then they have no idea what he is talking about and feel very very stupid, while I'm standing there with this look on my face
