I remember when there was the big spinach 'recall' with salmonella, my family and I went to a subway, this guy in front of us insisting on having spinach on his sandwhich even when they told him why they no longer had any, he continued arguing that he needed some, even if it was bad. Quite adament.. He ended up being forced to leave the building.
Sorry, what Sylvie said just reminded me of that.
