Very bad service

I have being placing large orders at KFC Lambton for the past 2 weeks. On Thursday 25th October, Events KFC Lambton manager refused to take my order and advise that before placing an order i need to come and pay first then go back to the office to confirm my order. I find it very difficult to first pay before placing an order. He mentioned that their procedure changed for placing order, but what amazed me is that from the 15th October i have placed large orders and the driver collect and pay and all of a sudden the procedure changed. My question was why would the fast food restaurant have contact details on the website to place orders and never mentioned anything about making a payment before placing an order. He further mentioned that i can report his feedback to Hello Peter and that i can order from any other restaurants if i am not happy with their procedure. What kind of fast food is that?
