“Any allegation that fake stamps have been purchased at a Post Office is extremely serious. The implication of such an allegation is that one of our postmasters, or a member of their staff, has obtained fake stamps and have chosen to sell them to customers rather than selling legitimate stamps that have come from Royal Mail’s secure printers.

“This is why we insist that any customer who thinks they may have purchased a fake stamp from a Post Office must produce an itemised receipt so that this can be looked into further.

Fucking ass covering bullshit. Just ignore the most likely reason, which is that your readers are malfunctioning, and avoid investigating because who the fuck keeps receipts for stamps?
