Monday Brain Teasers: Free beer!

The bar around the corner from my office sells beers for $6 a pint. Every pint comes with a token, and once you have collected four tokens you can exchange them for a free beer. How many total beers can I drink if I walk into the bar with $60? (Tipping is not permitted at this bar, and the beers are not taxed).

Those are some mighty big beers you girls have there . . .
