In a moment of weakness a friend recently signed up to the British Red Cross through a street vendor. A week later he received this card from the woman who talked him round.

I don’t see this level of service from my bank, landlord, insurers, accountant etc and other they take considerable more than a fiver a month from me. I’ve heard investment banks struggle to do this for clients that spend 7 figure sums every year.
A small commitment to remember a few points from a 5 minute conversation goes a long way. That’s service.
