I've said for years, the only thing a Home Depot or Lowe's employee knows is how to pass a drug test. They usually can't even tell you what aisle something is in, so if they start talking about which tool or how to do something, run - don't walk - away as fast as you can.I've noticed this in all aspects of retail these days. Want piss-poor advice on how to remodel your house? Ask most of the people at home depot. Yes, there are a few "experts" there, but most of the employees are just rubes who need a paycheck. I don't begrudge them for this, but the fact of the matter is that in most retail establishments, the chance that whomever is helping you actually knows more about the subject at hand than you do seems to be quite small these days.
In decades of going to those two crappy stores, I met one guy - ONE GUY! - who knew what he was talking about. He helped me rig up a toilet-mounted diaper sprayer out of dishwasher, air compressor, and toilet plumbing parts. The rest of those I've met are tits on a mule.
