Charity refund system

I'm not so much suggesting this, as making a prediction.

Recently I was forced to take a refund from a supplier of a grass cutting machine. I merely mentioned to them in an email that I had improved the design of the grass collection basket myself by means of adding a spacer to the structure with the effect of preventing the basket from collapsing every time it was removed to empty it. This hack, I maintained, had reduced my frustration no end.

As an aside: I find that these are the types of activity which one finds oneself pursuing ever more frequently once retired.

Unfortunately the supplier interpreted this as a complaint and sent a replacement grass box. Then when I explained in a note that this one had exactly the same defect as the first one, they sent me another, the same. I messaged them to explain that I hadn't been expecting any replacement grass boxes at all, merely pointing out a simple opportunity for improvement. They then informed me that I had been given a refund to the tune of £35 (35 GBP).

I decided that the thing to do with this undeserved, unexpected and unsolicited refund was to donate it to the Red Cross.

So, pairing this experience with the observation that chugging is nowadays programmed into most electronic payment machines; NO I do not want to donate £0.03 of my income taxed balance to the bloody polo player's benevolent fund, thank you very much- I extrapolate my own experience to predict that many online retailers in future will inevitably offer the option of donating a refund in whole or in part to a charity of your choice.

A good thing? BUN if so. Me, I'm undecided.
