At least 3 times ... all in a bank I worked in. Cut long stories very short ... 1 . Mysterious odd £5 notes went missing in bundles of notes that has customers name on ... I had a word with my manager had a straight swop with someone else at another branch ... didn't stop ... even a full bundle went missing ... glad it didn't stop as no doubt would have suspected me ... spoke to the inspectors at the time ... she had told lies etc when having time off aswell . 2. When people had to pay for a service, I checked this customer had paid ... didn't have to but I did ... I said you haven't paid hence she said I have a cash receipt which she showed me , I spoke to my manager later about it ! Cashier even implicated me & another girl as we wrote out credit slips, but had the cashier stamp on it who accepted it, quite a lot of money, did it across loads of customers . 3. I took over a till & it was a bungle short of money, as I had no one by me when I took it over , I was partly to blame , even took it to the union ... so my name was on the short, I remember someone saying to me she trusted me ! A few years later I spoke to someone on the phone & asked how this person was ... his reply got the sack, her till was over, she had money then customer came back a few weeks later not gone into his business account ... to me I am most certain this was the person took the money when I worked with her , at the end of day have to check no money is left in the tills ... I know of others aswell ... even people you class as friends!
