It really doesn't matter how many I may or may not have had lost in the past. I am old (and ugly enough) to know that when things do go wrong, it will be with maximum inconvenience. And multiplying the incompetence of two organisations that are famed for incompetence doesn't cancel it out.
It's f*ck all consolation, when the cheque goes missing, to hear someone say "that's odd. Never happened before."
