Hi, this is my first post here peeps so please be kind. I'm after some advice regarding the think 25 policy. My husband is a delivery driver for a well known British supermarket. He has an impeccable work record, never been disciplined for anything. Recently he failed a test purchase, the recipient was 19. He has no recollection of the delivery and doesn't feel he has made a delivery to anyone who looked under 25, hence why he hadn't asked them for ID. After going for a disciplinary meeting he has now been told as a consequence he has been given a final written warning!!!!!! Wtf? Is this normal? Having never had any warnings to make one mistake to get this? The person wasn't even underage. I would really appreciate any advice, they have told him he can appeal.
