Like recent cases of Chinese not honouring their bids at auction, so too it would seem one of the members of the ruling Al-Thani family in Qatar is not paying for his purchases.
Like most businesses, the concept of trust is paramount. I don't suppose it explains why, but my recent registration at an auction house in Germany has resulted in a much more thorough and detailed requirement to be given approval to bid. Happily I started the process well ahead of the auction, otherwise I would have missed out.
Similar bureaucracy has affected a payment I was due to receive from an investment plan I have been paying into for about 25 years. It matured on 1 November, and I still await funds, perhaps delayed because I initially but immediately rectified an omission to provide them with a copy of my passport, and proof of my address, despite requiring them to repay the funds to the bank account from which they have been taking the premiums over these many years. There have been some choice words exchanged. Perhaps further will be required.
