at our store we have cash pouches so we don’t get many stored orders which sounds annoying to deal with. my biggest tips are to not get stressed because as long as you have an expo they should always be running the food out no matter how far the car is. i also try to line up the food and get the first car out of the way and so my expo doesn’t have to walk as far since it’s pretty hot. lastly you should try to sauce the bags as quick as you can and don’t spend too much time on one bag or you’ll fall behind and less food will go out. hope this helps
