We can keep the supermarket cashiers, we just have to demand it. Always choose the full-service line, and complain loudly if there are not enough cashiers to keep the line short, scoff at any suggestion to use the self-checkout and demand to speak to a manager and corporate. As I said elsewhere, one person can only do so much, but when a million people keep doing it the mountain will have to move. I feel personally responsible for the installation of these cashboxes by insisting to pay in cash every single time for the past several years.
