I typically despise Home Depot, but when I needed some help figuring out their propane tank exchange system (it is different than in the Bay Area), I walked in and was assisted immediately(again, something different from my HD experiences at home).
My mom was with me, and we decided to check out their ceiling fans as the one in my Grandma's bedroom conked out and she had a list of requirements for a new one and even though at 89 she is quite internet savvy, she couldn't quite differentiate what was what.
Sadly, we left without a fan but did get mom her new propane tank (I am quite the cook and did not learn from mom) as she relies on the bbq for just about everything you can overcook :)
Mom also said I got the help I needed right away because I am tall, and under 60. Who knows, but I was glad to be in and out without any problems!
