I'm sure I've told this one before,but here I go again....
I worked for Halifax Building Society. Computer system at the time - if you wanted to draw some money out meant inputting customers account number, which would then print out a withdrawal voucher for the customer to sign..
The gentleman concerned's surname was Watts.
Unfortunately his initials were T.W.
So the name on the withdrawal voucher came up as " TWWATTS"
True story
