"Of course the real reason the US is phasing out tin cans is that the chemical name sounds like 'satanic'"
I think that the guy who said this was one of three men, all in their thirties-forties and fairly smartly dressed. Wouldn't amaze me if they were advertising people, there are some agencies in the area.
I just did a web search and can't find anything that looks like this sort of nonsense, but the chemical name for many tin compounds does begin "stannic" and that isn't far off being an anagram if you are deeply stupid. Anyone know anything about this?
