"WHAT'S THAT GOT TO DO WITH THREE COFFEES?"
"It takes three coffees for my brain to spin up to complex problem level. At 1 coffee my problem solving toolbox is unlocked but closed, and at two coffees the tool box is open, but only to the first tier."
"What's the first tier?"
"That's where I keep the hammer and the axe."
Good Simon.
