Went to get tube put in my front tire. They first told me because of the nature of my flat that I would have to sign a waver. I totally understand stand that. But then they declined to fix it after I agreed to sign the waver. The long haired shop manager has a loud mouth. I overheard his smart comment about me going to a parts store and buy an inner tube and fix it myself. He was saying that to his coworkers. Which not that y'all care. I'll never buy a damn thing there again because of the smart mouth hippie shop manager.
