Disappointed customer

I am very disappointed in the way the staff treated us at KFC no greetings and no thank you. Not even a smile on their faces. Another thing Im bothered with is that they say they don't sell the zinger burgers with the zinger sauce anymore. Do they even know how many customers they'll be loosing because of that..Everyone I know who likes zinger burgers only buying it because of the sauce. Although everything is just in moderation.
