It's karaoke night at the local bar. A group of 5 friends, who seem to have a knack for mathematics and a love for K-pop, walk in and order 3 beers each. One of them mentions they're celebrating a birthday with Chinese food later. Assuming the bartender doesn't have a problem with them being there, how many beers will he have to pour in total?
