If you find a shopkeeper who will refuse to sell you something on the basis that it is not right for you, you have a gem.
These people may be hard to find – but if you enter into conversation with them over a regular basis -and if it is a genuine and respectful exchange…you can find a whole new world of intelligent help out there.
I talk regularly to the family who run our local post office agency – and to the lady and the chap who run the Asian food store in the shopping centre. I talk to the man who runs the bottle shop, and to the lady who is teller at my local bank. The result is I get told how to cook well with the Asian ingredients, when to change my deposits for good interest rates, and how to send postal items safely at low cost.
Occasionally the bottle shop man warns me off a dud or mentions a good deal. I am always repaid for listening.
Moral: Your local retailers are human beings who appreciate being treated as such and who will make your life better if you recognise the fact.
