No. A byproduct of self checkout has been the downward pressure on the quality and professionalism of cashiers to the point I'd rather do it myself than to subject myself to a level of incompetence that borders on feeble.

Cashier is not a career path many aspire to, but like any job there's a floor. I'm willing to admit maybe it is my area or maybe only the places I frequently, or leaded gasoline poisoning my brain to the point of overblown irrational anger. BUT I long for a courteous, competent experience at any service establishment. I expect a 50/50 chance at a positive experience anywhere I go that interacts with the service sector. Maybe it has always been that way.

But, yeah. DIY as much as possible.
