I always use the self checkouts at Home Depot. You just drag every item across the scanner and then pay. If something is too large to scan, the assistant will hand-scan it for you. At the grocery store, it's a totally different story. Every time I try to use the self-checkouts, I end up regretting it. I think the difference is that the grocery store machine attempts to make sure you don't steal anything by verifying that nothing is put in the bags without a scan, or that the weight of that something agrees with what is scanned. This never works, it always says "unexpected item in bagging area", and then you have to wait for a store person to clear it for you. It ends up taking forever. (Not to mention the vegetables without bar codes that the actual checkers have all the codes memorized for but that you have to search through a long list to find...)
