The first and only time I used such a place, the Jiffy Lube in Pacifica off Skyline, the smell of burning oil graced my driving experience for the better part of a week afterwards.

You see, I had brought quality Mobil 1 full synthetic oil in quart bottles, which the career oil changers didn't seem to understand how to pour without spilling everywhere. Pro-tip: the offset spout is supposed to be at the top, not the bottom orientation.

Oil changes are inherently a probable interaction with either children or clowns. And I'm saying this as someone who did oil changes as a summer job, back before I had a driver's license. The things I've seen... I pity the fool who relies on random third parties for maintenance. EVs are a potentially huge improvement in this department.

To be honest, you showed up with some weird bottle the people working there probably have never used and you got the expected results. You do something like that with anything and it would probably result in the same sort of situation. I've never had an issue. I know how to change my own oil and still pay people to do it. Not worth my time when its so cheap to have someone else do it in 15 minutes while I sit there looking at emails. I can get any expert or schmuck or handy relative to work on my car for a range of competitive prices. Legally I have to pay tesla $22,500 to replace a battery. Not much of an improvement for the consumer.

> you showed up with some weird bottle

There's nothing weird about a 1-quart bottle of Mobil 1, it's the same basic form factor retail oil quarts have been sold in since they stopped being steel cans, i.e. before most Jiffy Lube employees were born.

The problem isn't the bottle, the problem is a combination of carelessness and incompetence. Which is what you're going to get with a high probability at these low-level positions, good luck with that.
