My first real job was in a local newsagent, where, for £1.60ph, I learnt the essential skills of how to face rows of Kit Kats, smile politely at rude customers and restock the cigarette kiosk one-handed (we had to amuse ourselves somehow). Those first shifts taught generations of young people the importance of turning up on time, how to work as part of a team and, crucially, the satisfaction of earning their own money.
