What's with the Samuel Gawith tobacco shortage?

"The popularity of Samuel Gawith has just exploded in the last few years worldwide and they have a really small factory with really old machinery and they can't grow production without destroying what makes it special. A container comes into the United States (I don't know when the next one's coming) and we buy as much as we can out of the container. It gets put on pallets and then we turn around and put it in little tiny boxes and it's all gone in about five days, sometimes only three days. There's all this pent up demand for it and there's no way Samuel Gawith can make enough and that's what happens." - Sykes Wilford
