Credit card facilities continually faulty

Hello, I've been living in the Brackenhurst area for years. For years now I try to use the drive through at the KFC yet EVERY time they inform me when I get there, that the credit card facilities at the drive through isn't working and that I should park my car and come pay inside. If this happened once or twice or maybe 3 times, it would be okay, but this has been going on for years now and I don't even visit KFC that regularly. Which just goes to show how shocking it is that this has been the case for so long. The last time I went to KFC and I was told that the machine was still not working, I actually decided not to order from KFC seeing as it's too much trouble for them to fix what is a simple problem. I instead went to an alternative fast food restaurant with a functioning drive through. I will never visit KFC again.
