I was ordering parts for an out-of-production machine where it's been replaced by a similar but not identical in some aspects machine. I had made errors in ordering the wrong items by ordering some for the new machine. They didn't know what I had, but they were so astute as to pick up the odd combination or parts. In the end they cancelled the incorrect order and confirmed the correct parts, enabling me to start afresh. So it's not just that they delivered what I ordered, nor that I confirmed everything at the weekend and the parcel arrived Tuesday having been despatched Monday, it's that they care about the customer getting the right outcome even if the customer would have been at fault.
