I like it for other customers too.

Nothing is worse than standing in line behind someone who is talking the ear off a cashier while you’re waiting to get your shit and get the fuck on with your day. Or them taking forever counting change or dealing with their obnoxious children or taking forever grabbing their shit and getting the fuck on.

I never have to worry about that with self checkout. Especially since the lines are usually set up in a way that everyone waits for a self checkout to open than having a single line for each checkout. I suppose the fix for my secondary issue would be to do that for human cashiers too. Just one line waiting for any register to open up.
