By not fostering loyalty you have made it easier for your customers not to shop you. Make no mistake, an AMEX is a status symbol. By not taking it you are also not recognizing his hard won status, you are pissing him off.
I believe that the loyalty I have fostered with customers is above
and beyond whether I take Amex. I believe I have products and
services that set me apart from other retailers. I believe the skill
and knowledge I have sets me apart from the businesses that take
Amex.
There is a benefit to the customer to shop at my store that is
greater than the benefit of not being able to use the Amex card. I
believe there might be people who will not spend money where Amex is
not taken. I believe this type of person is so far and few between it
is a moot point.
If you want to shop at my store, leave your Amex at home. I believe I
have a sense of whether I am losing sales by not taking Amex.
I believe that some of my customers would rather the status of having
my work over the status of using their Amex.
