O.P. here.... Apologies for my own thoughts and post being "wrong" ????. Thanks for the education and corrections - send me the bill ????.
The story is about my son who works in a 7-11. He is not the sharpest tool in the shed as his brain was damaged, being starved of oxygen for over 2 minutes during birth. He's a lovely lad and although a bit "slow", works hard to the best of his ability and tries to please everyone.
He was given a job managing the stock deliveries and re-stocking the shelves etc, which he has been doing very well at. BUT, the other day I found out that he has been put on the tills, handling banking transactions that 7-11 now does. One day his till was down 4,000 baht due to crediting a depositing customer's account for 17,000 baht instead of 13,000 baht. The customer never queried the 4,000 Baht extra credit. Subsequent review of the till CCTV showed up his difficulty counting all the cash and his counting error. 4,000 Baht was removed from my son's pay packet at the end of the month.
It's a life lesson that will stand him in good stead, if he is able to learn from it, but I can't for the life of me understand how an employee employed as a "box-mover", with zero qualifications or never having passed internal financial competency tests beyond scanning a barcode, can find themselves working as a bank teller with full personal financial responsibility for sizable banking transactions.
Thanks for everyone's contributions to this thread.
