After queuing at the check-out, having his few purchases scanned, Paul was out of the building and half way across the car park before he realised he’d forgotten the cream. He tried to remember if Trevor hadany, but thought he best play safe and get some. Coming to a halt, he debated whether he should put his purchases in the car and then go back to the supermarket, or take his bag back inside. Fearing they’d want to make him pay a second time for what he’d just bought, Paul thought it better to go on to his car.
