The only places I've found that refuse AMEX are very small mom and pop operations. And of those, many don't accept cards of any type: cash only.

Fair enough, it's probably not as common as I think and is more of a reputation.

Costco?

[Edit] -- And I've frequented several independent coffee shops that are cashless.

Costco doesn't even accept Mastercard (credit cards), so they're kind of a unique case here where they intentionally choose to only accept one particular type of credit cards.

[SoftTalker]

Guessing they have their own branded card that they push you to use?

[CobaltFire]

Correct, and it used to be AMEX.
