Jiffy Lube hostile, dangerous treatment Portland Maine

Jiffy Lube #1806, work order #1304

On August 15, 2017 I needed an oil change for a stretch limousine. They drained the oil, then told me it was $88.99 when it was too late to go elsewhere, and they don't use Mobil One. I told them from the start that I only wanted an oil change. I was in a bit of a rush and didn't need anything else. We maintain our vehicles just fine, and had 4 new tires put on literally a week earlier. They decided to check everything anyway, making me wait about 40 minutes. When I went to pay, Zachary the cashier, with an air of disinterest said that they adjusted the tire pressure. I told him that the pressure had been checked twice this week (by me and the tire center down the street) and was fine, and asked what they changed the pressure to, his disinterest became repressed hostility and he replied "How am I supposed to know that? I just got back from break!" I wasn't interested in garganutuan battle over the question. The insinuation was that his lunch made him incapable of answering such a stupid question from a customer and that was it, understood? 

A week later, the way I was treated was going through my mind because two people had told me that a tire looked low. After dropping my 8 customers off in the middle of Boston traffic, I went to a filling station to check the tire pressure. The proper max psi is 50 for all tires, but they had lowered the rear tire pressure to under 40, and the front ones to 60 psi, endangering me and my passengers for a service that I didn't want, and subsequently wouldn't discuss. I was complaining in the waiting room about the high price for a 40 minute oil change. I don't know if it was revenge or gross incometence. They had an unwillingness to keep their hands off the area of my car I asked them not to touch, but Zachary certainly instilled in me that I should not trust them. His hostility may have saved me and my passengers from harm, but I will never know if they did it on purpose or not. I will not give them the chance to harm me again.
