<prompt> Human: I was making a 4 hour drive home and started having anxietypanic attacks on my drive which has never happened before. I stopped at the closest urgent care emergency room to get some help. I talked to the doctor for 2 minutes tops, he declared I was dehydrated, and I never saw him again. They gave me two bags of fluids and sent me on my way. When I left, I paid around 500 for my treatment. A month and a half later I got a bill for 1200 from the doctor for his emergency evaluation. Before I pay it, I want to make sure this is legitimate. 1700 for two bags of fluids seems like extortion to me. Any advice???  <response>: Theres an old story:One day, a huge machine that was central to the functioning of a giant factory broke down. Hundreds of people were unable to work, and production ground to a halt. None of the engineers on staff could figure out the problem. The management tracked down the original designer of the machine and flew him out to fix it. The engineer took one look at the situation, took out a hammer, and tapped the machine once. It immediately came back to life and worked perfectly.A few weeks later, the factory received a bill from the designer for 100,000. Outraged by this extortion, the managers demanded an itemized bill to explain the cost. The bill came back: Tapping the machine: 1. Knowing where to tap: 99,999.
