Yes, it is true!
You need to look at the details page to see which CC the location accepts for giving idine credit. Not all CCs may give you credit.
A restaurant may accept AX, MC, VI or DS for payment - they may even accept
cash to pay the bill!
But they may only give idine credit if you use your MC or VI. Some may give credit for MC but not VI.
It is always best to check the details to see which CC gets idine credit before dining!
