Bay Area restaurants charge $50 'vomit fee' for guests taking bottomless mimosas too far

Home Plate on Lombard Street in San Francisco has a similar policy, reported SFGate. Signs posted around the restaurant and on the menu asked diners to "Please Drink Responsibly. $50 cleaning fee per person for any incident incur as a result of intoxication."

Other brunch restaurants in the Bay Area use "mimosa fairies," servers devoted to monitoring the intake of guests.

Which type of liberalism is this?
