It sounds like you been around the block a couple times. And since I never use quickie oil change places (typically with the trenches), a fave experiment I'll do with any new shop is mention to the manager, "I haven't seen the underside of this rig yet, and would love a chance to eyeball things once it's in the air, ok"? A "Yes" and there's potential. A "No, insurance won't let customers in the work area.", and it's unfortunately going to be a 'one and done' for that shop.
