I've worked at Coles for 10 years and now Woolworths for 3. Theft occurs literally everyday and we are so fed up with it, we usually don't even bother.
I have the data and each week thousands, if not tens of thousands of dollars worth of stock is lost not just theft but perishables, etc.
This is a pretty small store but we still end up making hundreds of thousands of dollars a week, mostly profit.
We adjust for stock loss and theft and pretty sure some type of insurance is used to pay for these losses. We end up being the winners and the thieves not only go home with our property, but a guilty conscious and they're the ones who spiral out of control and obviously have more problems in their life than solutions.
Also, Yes we can easily find out who you are via your cards or cctv but don't bother with all our other duties. We have screenshots of repeat offenders saved on our computers and even loss prevention officers have access that can apprehend you if they wish.
An EXTREME example of this....im sure you have all heard of the murder case of Celeste Manno by her crazy stalker.
According to published court documents..... (in the manner of Luay Sako v DPP 2023 ... 'he purchased a 'mint' brand kitchen knife from woolworths and the staff/manager found his identity by searching his scanned Everyday Rewards card and credit cards, etc. He actually used this as the murder weapon.
So yes we can find your details but petty theft usually goes unnoticed.
