The blood from a stone thing is really reaching a tipping point.

Me and my girlfriend haven't gone out for a meal in over a year. I don't know anybody who regularly goes to restaurants anymore and if they do it's to see a live band and drink booze they brought from home in the parking lot.

At a certain point the people will theoretically just not have any money to spend and then no amount of business school wisdom is going to get somebody with $5 to pay $20 for a burger.
