When I worked in Greggs we were told that if you spread sales evenly over a week, that store wouldn't make profit until Saturday afternoon.
Shoplifter 'uniform' north face and armarni !
Lots of customers paying for some items, but nicking others (red bull and lucozade in particular). And the more customers which witness others doing it, the more that try it out.
It's frustrating and disheartening as staff - especially managers - as our performance was rated on waste and availability. So if someone steals the last cheese and ham baguette, you have to make more, usually for them to be stolen again! So takes staff time as well as ingredients etc - knocks all your stock out of whack.
We had builders stealing to order for co-workers, until one day my colleague followed them and informed the site manager.
