So you're at Heathrow at 6am, three pax in the lounge, each with a drink.
One has just got off the flight from Hong Kong, so the body clock says it's 2pm.
One has just got off an early departure from the West Coast of the US, so the body clock says it's 10pm
One is about to jump on the shuttle to Glasgow
In fairness, all three of them deserve a stiff drink
