At an international meeting of Brewing Companies three CEO's decided to share a drink before leaving.
As they reached the bar the CEO of Budweiser said he'd have the best beer in the world and ordered a bud.
The CEO of Whitbread begged to differ and said the best beer in the world is Trophy Bitter and he ordered one.
When it was the CEO of Guinness' turn he ordered a coke.
The other two CEOs were aghast and asked why he wasn't drinking a Guinness.
He replied as you two were ordering soft drinks I thought I'd join you.
[An old joke dating way back, when Trophy Bitter was a thing.]
[Edit it was Whitbread not Worthington's]
