$20m / year is a mom & pop business?
Contrast this with the fact that an average Walmart does over $100 million a year in revenue (though Walmart's margins are closer to 1%), and it's actually not that huge.
So I thought I'd throw this comment in here in case others were misreading it as I did.
They had employees, but were still entirely owned and managed by a literal "mom and pop" whose children I went to school with.
