Previously an employee scanned and took my payment. Now that 'employee' is me. What is my upside? Generally I try not to work for free whilst making other people richer...
Well if the other employees screw up they get a warning and maybe some direction. If you screw up at your job you'll get accused of shoplifting and maybe get the cops called.
Heh, I always put eggs on the bottom of my bag. Those cartons provide a nice base and are designed to hold a lot of weight. But, I agree, I prefer self-checkout because I can organize the bags as I want them.
