First call resolution

When I use the headline first call resolution I mean that I shouldn't ask several people before getting the correct answer. My boyfriend and I went to get a quick snack and when we got to the windows to place our order, the woman at the windows was not interested in us or didn't want to answer us regarding the questions we had. We then just placed our our order and rive to the next windows. When got there there woman there was just as dazed as the other, they might be tired because its night shift however it's what they signed up for. They need to understand that respecting the customer is not an exception it's the rule. I'm disappointed with service received that I couldn't eat my food. I'm not sorry for saying this but I'm no longer going to be returning to that KFC or any other because one rotten potato spoils the rest.
