Matters which Home Depot and what hours. If you go during slow time. Some old person who is doing this as a retirement gig will tell you what you really need etc., but I’ve also experienced not being able to get someone while it’s busy and having the department-specific person MIA. Many parts are missing even if the website says they are in stock because people steel them. I had an employee tell me that the didn’t sell the individual plumbing part that I needed, but winked and nudged that I should buy a kit that had it and return it without that piece. He was like, either that or essentially steal the part out of the box when no one was looking. That’s your ghetto Home Depot. In the more upscale town Home Depot, they are better stocked and less busy, so generally more helpful.
