oh.... this kinds of machine is rare here.... but when we had one at school we were spending the whole break (20 mins) asking each other
me:"you SURE ist 23B?"
friend:"yeah,it is!"
me:" you sure? cause if i'm getting the RC,i'm gonna make you drink it,and after you drink it,i'm gonna shove it to your ass"
friend:"ok,let me check it again...."
but now we have a machine with six buttons,and on each button there's the logo of the drink,so if we don't know what to to choose,we got 5 meters back,and slam into the machine... so fun...
