My dad’s mate Mo always drinks John Smith’s Light at the pub.
I’m not sure anyone remembers how it had started.
Whenever Mo orders a pint, the bar man says, “Hang on Mo, let me switch it.” He clicks a little button under the pump behind the bar and, just like that, starts serving Mo his John Smith’s Light.
I don’t know at what point I found out about it. I still have the innocent memory of being amazed by the “Light” switch, though it has been years since I was let in on the joke.
I don’t know how everyone has kept a straight face – how no one has told him for over 15 years.
But even now, Mo still drink John Smith’s Light.
He swears it tastes better.
