People usually drink it by biting a little hole in the corner and squeezing it into their mouths. This, however, is not a good method if you are trying to drink it while selling books, because you’re committed to finishing it all in one go. If you should take it out of your mouth to explain the literature you’re selling, you might try to hold the hole shut with your fingers. This is less than effective, though, so bisap runs down your arm (it’s nice and sticky with sugar) and onto your dress, since you’re frantically holding it away from the books. Now I untie the bag and pour it into a bottle.
