McDonalds operates entirely off of a system. From taking the food order , to slapping the sandwiches together, to packaging the food and handing it to the customer. If you're forgetting tools - then you need to refine your system. Last week I forgot the 3" suction hose for the water pump. Luckily I realized this before we passed by the rental store. $15 to rent the hose for the day. That's better than 2-3k for a trailer that we would not store a bulky hose in anyway.
