Oh, well, the service could have been better, but I kind of refuse to work for free, and without any benefits. And then someone else stick the money in their pocket to live a better life. That is not my idea of "fair".
That's why I always go through the manned check out lines at my local stores... Even if I have to wait longer than the self serve... I want to support someone's job to be a cashier and not do their work for them so the company can phase them out....
