About 6 weeks ago I was browsing in a shop, the shop sells fairly expensive sporting items. Had a nice chat with the owner who advised me what I should buy and we went on to have a bit of a chat. At the time I didn't have enough cash on me, so thanked him for his time and went on my merry way.
This weekend (remember this is 6 weeks later) I went back to the same shop. I walked in and the shop owner actually greeted me by name! He must have had literally hundreds of customers in the meantime so I was amazed and very pleased.
Of course, I ended up spending quite a bit of money. I'm not sure about the moral of this story, however, I do know that if I had originally walked in and been treated as part of the herd, I would probably have gone to another shop to have a look to see if I could get the items cheaper.
I think I'm saying; treat your customers well, and they'll treat you well in return.
