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.
Ed visits and cares for Walter. As Ed prepares to leave, Walter offers him $10,000 to stick around for two more hours. Ed takes the offer but only for one hour and the two start playing cards. Based on the earlier exchange, Ed’s reservation price for each hour is above $5,000 but below $10,000.
