San Francisco's housing market is so expensive the city is considered to be in a crisis.
It's so bad that restaurant workers are leaving the city, because it's unaffordable.
This is causing changes to restaurant culture and the service industry in San Fran.
In fact, several restaurants are having customers order at the counter vs. having them being waited on at tables.
San Francisco isn't the only city to see this problem. New York and Washington are also experiencing this.
