That's great. I'd not be opposed to you having the option to do those things by yourself. Personally though, I'd rather just have someone who's paid to do it than have ads pumped into my ears as I pump gas or mess with the finicky self-checkout machines as someone watches me anyway. Now, if giving these things up would result in those employees ending up with a better station in life or more meaningful work, that would be something to consider. But in reality, the only result of forcing me to do those things will be higher corporate margins. So, no thanks.
