Wendys drive thru 31. 5 second speedrun

Even faster than my other 2 speedruns. It s ridiculous how fast they can get my order to me. This video was taken at 11:40 am on a Wednesday with one car ahead of me. I ordered a Baconator meal. I paid cash and received my change. I asked for ketchup at the window. It all only took 31. 5 seconds. How do they do that
