So, am now in the Costa Coffee shop. I tried to pay for my double espresso and croissant with my Costa Club Card .... "Sorry, we don't have the machine here." Admittedly, it does say on the back of the card "valid for use only at participating Costa stores", but there should still be a sign up somehwere to say that they can't accept them here. Black Mark, Costa. Get those machines out to your stores. This customer wants that facility, and the customer is always right! I shall leave a comment on the Costa site.
