bad service

<p>I go to sloane square to get myself a box master. Drive thru card machine not working. I have to go into the store. It's Friday lunch rush. I'm 2nd in queue. Wait 10 mins to be served as there is 1 person taking orders. She gets customer ahead of me order wrong. Takes 10 mins for 4 people to assist her to correct the mistake. Now the queue is out the door. I ask is there only 1 person. The lady didn't greet me but clicked her tongue at me. </p> <p>Another 7 mins later I get my food. When I open my box master it has no mayo on it, chicken is dry and tasteless. </p> <p>I will NEVER order at that kfc again. </p>
