A lot of those things I don't mind doing if I have the time, and can realize a savings in dollars or schedule.
But I have this "old guy" aversion to things like self-checkout. Yeah, occasionally it could save some time, but I'm not real interested in working for multi-billion dollar corporations for no money. When store droids "invite" me to use the self-checkout, my response is always, "Sure. What's the employee discount?" Since there never is one, I choose not to be an employee.
Wonder what would happen if I injured myself on their equipment while working for them?
I'm sure I could gripe some more, but dinner's ready!
I guess I too have that "Old Guy" aversion to self checkout. I always prefer to give somebody a job checking out my purchases. I've done the self checkout thing a few times, when the lines at the "human" checkout were just too long for the time I had. But I use the "Manned" checkout far more often.
