I arrived with the truck in the morning around 9 am and there was only one truck being serviced, I just wanted them to look at a problem I had, around 10 am they told me that I had to replace the release valve, and put on a mudflap that I had with me that I requested to be put on, they sent me an estimate of 600 dollars, a labor of 360 to replace the release valve and 87 dollars for the mudflap, around 3 in the afternoon they still had not serviced the truck and no one had entered the service, I spoke to someone and then they serviced the truck and in less than an hour the truck was ready to leave, I don't understand why they charge 360 dollars for a 30 minute job and leave the truck stopped for 7 hours in the shop, wasting my time and money, should I charge you for the labor? Time spent on cell phones and not working, and then charging customers for their time, unfair and expensive
