I am wondering what people would do in following scenario.
You are shopping with your family. You buy 2 full trolley load from Coles or Woolworths and then walk into Aldi for some additional stuff. When it's your turn at checkout, the staff asked whether this stuff is from another shop. You say 'Yes' but they insist on looking into the bag though you have shown them receipt(proof of purchase.
As regular customer, they are doing their job. Wouldn’t be worried either as I don’t have anything to hide.
Would be interesting to know their perspective if they had a bodycam.
