KFC Meadowdale mall

KFC at Meadowdale mall needs to advice people that they have card facility issues before you enter the drive thru. This is the second time I have been there in 3 weeks and they have card facility issue and you are only notified ones you are in the drive thru. I just spent 15 minutes idling my petrol out just to get out of the drive thru as I don't carry cash to pay for things. This is really ridiculous
