Bad customer service

I was on the drive thru line for about 30 minutes, finally I got to the intercom to place an order only to be told it's cash only no card payments. I asked the drive thru lady why was there no sign or indication that we can't use the debit card, she just told me there's nothing she can do. I said it's fine but I will not que inside, I'm jumping the line. She quickly ran to the inside kiosk to tell the lady taking orders not to serve us. We were told burgers are finished. 10 minutes later we placed the order via phone and it was captured. Then my wife phoned the supervisor and told her what had happened. We got our meal for free thanks to the supervisor. Thank you supervisor, didn't get her name, she is a star. The other two ladies should go back to cleaning or packing stuff coz they don't have customer care. Five stars for the supervisor
