Long wait at Drive Thru

Good day,<br> <br> We were at the above mentioned KFC's drive thru service on Saturday 21 March 2015, we waited approximately 20 minutes for our order. I am sure I would not have been so angry if someone had told us what the delay was. Instead after 15minutes, my husband goes to the window and asks what the delay is and they reply that the chicken will be done in about 1 minute, nevertheless, about 5 minutes later we are served as there were 2 cars ahead of us. Please guys, customer service is important, the reason we do drive thru is for faster service. So next time please inform your customers that there is a delay.<br> <br> A very disappointed client.<br>
