SCENE: A BUSY BAR ROOM, WE SEE A MAN AT THE BAR WAVING A TENNER TO GET THE BARMAID'S ATTENTION
BARMAID: Hello sir, what can I get for you?
MAN: I'll have a pint of lager, please. John what are you having?
JOHN: Guinness please.
MAN: Tony, what about you?
TONY: My usual please, a pint of Old Peculiar.
MAN: And for you Kev?
WE CUT TO SEE A MAN IN FULL SCUBA GEAR
KEV (WEARILY): Just a lemonade for me.
MAN (INCREDULOUSLY): Lemonade?
KEV: Yes, I can't have anything else as I'm the designated diver.
