Reason #9,256 why business is so freakin' hard: guy takes a look at mustard. Finds out that plain yellow French's used to utterly dominate. Then one day Grey Poupon showed up and took a huge bite out of French's share, and now there are, like, a zillion types of mustard in U. S. stores. So he gets a bright idea: he'll do exactly the same thing, except with ketchup.
Only one problem: turns out "ketchup is ketchup" and nobody, apparently, wants anything different.
