It is easy to forget that English is not the first language for many readers of this forum.
Idiomatic expressions will vary in different English speaking countries and if taken literally can sometimes be misconstrued. The 'clear your credit card comment' is neither an instruction or an assumption that you will be using a credit card.
Similarly the suggestion that there is some inference that using a credit card implies that you do not have the funds to back up a purchase is as erroneous as that buying with large sums of cash would suggest that the purchase is being funded by criminal activity.
