It's an election year! That means in November, millions of people are going to stand in a really long line. If they get out of this line to use the bathroom or get refreshments, they could lose their spot, especially after the polls officially close.
This reluctance to get off the line got me thinking; is it legal, in the United States, to sell snacks to fellow voters in line? If I were to pull out a crate of fun-sized bags of potato chips and mark them up 500% after the doors close, I could make a killing. Of course, I wouldn't actually do this, as it's predatory and unethical. Could I, though? (Assume that my little venture is entirely apolitical, i.e. I wouldn't charge people differently based on whom they're voting for or where they stand on issues.)
