"If it was a stiff drink I wanted, I would demand an egg flip" quoth the guest with an air of juvenile defiance. "I'll have a 1940's beer barman". The barman now unsure how to handle the situation poured a normal beer (if there is such a thing) into a pint glass and handed it to the guest...."Pour me another 1940's beer while you're there" said the guest so the barman poured him a further pint of normal beer.
"That will be £5($10)" said the barman haughtily. "No it will not" said the guest, "I asked for 1940's beer and you pulled me two pints and 10p(5 cents) is all you're gonna get for the two".
