Walter drives to the desert to hide the cash generated by his methamphetamine enterprise but he runs out of gas. As he rolls one of the money-full barrels, he comes by a house and asks to buy the truck sitting in the driveway. Initially, the truck is not for sale but after he offers the man a large stack of money this changes. Next, we see Walter load the barrel in the back of the recently purchased vehicle. Each person/business has a reservation price at which they’re willing to sell products or services. For this lucky resident, it appears $10,000 was at or above his reservation price. If his reservation price was lower than $10,000 then he would hear producer surplus.
