I thought that only happins to me. Several years ago I had my tires changed at Crowell Bros. in Hoquiam and the also forgot to tighten on wheel. I was on my way to a charter on the penenisula and my tire fell off. Fortunately m clients car had a hitch and we made it to the river. That PM I called Crowells and the said to call a wrecker and have it towed to their shop. Then they would NOT pay the wrecker. They also would not buy me a new wheel but put on the ruined one and had me driving on it. Then I had a flat and went to a different tire place and they would not put on the wheel. The lug holes were ovaled so I had to bu a new one. Crowells would NOT pay for that either. So I have never set foot in their shop since. I was a 30 year customer with them.
I hope you have better luck with your dealer. See ya up North. fp
