Three married couples in South Florida have created a beer/cigarettes delivery service after a night of drinking and having no one sober enough to make another beer run. After cooking up the idea on a drunken Halloween night, they committed to the plan, took out business loans, etc., and have created "The Beer Runners."
For an order of over $20, they will deliver alcohol with a charge of $5 for the first three miles, and 65 cents for each mile over that. Their formula for success?
"You think what you would have to pay for court fees if you got a DUI, what's $10 to have beer delivered?" - Jon Fox, one of the owners
Here, we have a case where market incentives have created a for-profit service (beer delivery) that has significant positive externalities--that is, keeping drunk people from hitting the roads for a beer run. The question is, how long until a "sin tax" or something of the like is slapped on alcohol delivery services?
