TLDR: self-checkout available; service when asked; not too busy with customers
Home Depot is one of three hardware stores that I frequent if I need something quick like PVC pipe or mulch. This location is conveniently located next to the freeway and a Fatburger in case shopping for lightbulbs makes you hungry.
I came to actually pick up a toilet seat and boy do they have options. They have plastic, wood, wood enameled, and some with nightlights. WTF. Nightlights?!? Just turn on the night? Who goes peeing in the dark? Whatever. Prices are not the best, but they'll suffice.
If you're looking for help, look harder. There's not that many people on the flood and they don't even say hello. But if you ask them for help, they will be extra knowledgeable and provide input. Clearly they don't work on commission, but a simple hello shouldn't be that hard to provide.
