Ambling through the station this morning, I passed a throng of lobotomy eyed graduates trying to entice me with free cans of Pepsi Max.

“Try Pepsi Max,” a bespectacled, clean shaven and slightly pudgy youth called out. “Fat free and sugar free.”

Sometimes I can’t help myself. “Fat free?” I queried. “How much fat does normal Pepsi have?”

“Well, I don’t know the exact amount”, he replied, “but it’s quite a lot because it’s got loads of sugar in it.”

“Oh,” I said. “I see. Thanks anyway.”

Nw I’m wondering if I should have told him.
