No, I am not just in the middle of trying to buy Mayfair and all 4 stations! This week my wife and I were moving money from one bank to another to pay all the bills. The queues were very long, and so I joined the queue for bank Y. This was the bank where we were going to put the money in. My wife went to bank X to get the money out. We had previous phoned bank X and asked for them to keep £1800 for us to take out. My wife came into the bank and gave me a brown envelope with cash and then went off to do a couple of things in the town. I went to the till of bank Y and gave them the brown envelope. I said to the lady that there was £1800 in the envelope. My baby was screaming so I went to pick him up while she counted it twice. She gave me the receipt for the money and I left the bank. When I met up with my wife again I gave her the receipt as she is more trustworthy than I with keeping little bits of paper. She read it and said "how did you give the bank £1800". I said isn't that how much was supposed to be in the envelope you gave me. She said "No, they only had £1500 available, so I only gave you £1500. I thought you would have realized." (Please let's not even go to the place where we ask how she could have thought I would have realized!). Now I have bank X showing I have taken out £1500. I have bank Y showing I have put in £1800. I have receipts for both transactions. My question: will the banks ever notice? Will anyone ever notice? Should I even care? If I contact the banks what will they do? If I don't contact the banks what will they do? Or does this mean that Bank Y is funding my Christmas money this year? Any advice / ideas would be helpful. Thanks, NMAM.
