It is my experience that Lowes hires independent contractors to do installation and set up work. Ditto deliveries of some items.
It turns out, a good reliable independent contractor can easily get “covered up” Havind Lowes as a client provides steady profitable stream of work. The contractor is not a low paid Mexican but a reliable person who does good work.
Home Depot does the same.
I like Lowes too. In my case, when I needed PVC fittings, there’s were neat and organized, the other store (which I also like), not so much!
I won’t bash them either. While others here have some fondness for mom and pop stores, my only memories (from high school mainly) when walking the aisles and looking at stuff, was being told to get out - because they figured I would start pocketing things. I learned way more, faster, by walking the aisles at Lowes and HD than any other source, back when those stores first started opening, which was well before the web.
