Sophie's Sandwich Shop patron Louis Worth, a longtime user of Grey Poupon dijon mustard, could not bring himself to ask for the product Monday when he actually needed it. 'There's usually a bottle on one of the tables, but this time there wasn't,' Worth said. 'I actually said 'Pardon me' to the guy behind the counter, but then stopped in my tracks. I realized that if I actually asked, the guy would probably act all funny and say, 'But, of course,' in a rich-guy voice. So I just ate my turkey sandwich without it.'
