The buck stops on the manager's desk. He is the one ultimately responsible for how potential customers are treated. It just becomes "policy" to treat each potential customer with respect and attention when it flows from the top.
A friend from Savannah went to England and Scotland a few years ago for an extended visit with his daughter and her husband. He went to Purdey, Holland & Holland, and Dickson & Son. He told me that Purdey and Dickson treated him like he was about to write a six-figure check for a fine gun, but that H & H was very aloof and pretty much ignored him as he visited their establishment.
We have power, with this forum, to help affect change in situations like this by reporting how we are treated by associated businesses. Thanks for yours.
