KFC MANAGER RUDE.

I had trouble ordering on the KFC app it couldn't get past the payment screen, I then went to KFC BEN FLEUR, now I buy from this KFC nearly everyday and I've had my fair share of bad customer service but today I got fed up mainly because the manager was called after the staff member explained they can't really do anything with the app. I jokingly asked if they are fine with a negative review and the manager became really dismissive and looked at me with a disgusted look. She proceeded to say 'yes' in a very rude tone.. and just left me standing there like an idiot. I should also say, I work in customer services as well I know how to treat customers and how to help customers with any problems they may have.
