You are a retired military man who, over many years of service, acquired a mass of weapons and arranged deliveries from military bases. Opening your store in the middle of the desert, you will do your business. Your customers have a variety of requirements for weapons and you will have to fulfill them. Go to the counter and wait for the buyers, as soon as they come up over their heads there will be a desire, or rather, what they want to buy. Then go to your warehouse, there you can find a lever that lowers the goods. Pick them up and take them to a client who will pay you a decent amount. If you delay, the buyer will leave and the reputation of the store will decrease.
