Beags . I had an "account" but always paid cash.. Then I started getting invoices for a transaction I had long cleared. I let this build up for months with a stream of increasingly insistent incoming letters accruing as I was elsewhere. That was an odd year of transistion you will recall.
Funnily enough when I got back to the Towers and presented the receipt proving payment to the concerned party,there was little in the way of an apology. So I moved on.
Burtons were quite good actually !
