I'm a little obsessed with the Tabasco story.
First thing: people have a bottle of Tabasco in their house and in their restaurant. It solves their "hot sauce problem". If someone asks for it, you've got some. This is a very good thing for the Tabasco people.
Second thing: people only buy more Tabasco when they run out of it. Which doesn't happen so often, at least in most blue states. Replenishment only is not as good as people buying something because they like buying it.
And the third thing, the biggest change, is that there are now thousands of brands of hot sauce, many of which are far better than Tabasco, and millions of people are buying not one flavor, but several. And they buy more varieties because they want to, not because they have to.
