When I was young, back in the Dark Ages (the mid 70s), I would stop at the nearby Taco Bell after getting off of work from Sears. I would order two bean burritos with green sauce instead of red sauce and extra onions, and a mexi-melt. The price was 87 cents.
Today that same meal (yes, they will still make mexi-melts if you ask nicely) would be about $10.
