I've just had an email from an outfit called Scrivens Opticians, of which I haven't even heard let alone been a customer, titled "Mr Jones, It's Your Birthday Next Month!". As it happens, I knew that. The text of the message is:
It's not just wisdom that comes with age it's great discounts as well, and because you've got a birthday next month, celebrate your special day with 10% off your next pair of glasses when you come in and see us before the end of March.
Wasn't that a kind thought!
