Store managers have reduced the number of lines staffed by clerks. And a customer can, with occasional exceptions, forget about having anyone bag his or her groceries.
I guess this is because of price pressures from online competition as well as your typical corporate greed to reduce every penny that is paid to human beings who actually do the work.
What is making things even worse from my perspective is that although stores have continued to increase the number of self-service kiosks, they haven't exactly gone out of their way to make them user friendly. In one store at any given time, including the "rush hour" on weekend mornings most of the self-service kiosks are non-functional while at a different store across town the managers have altered the kiosks to not accept cash, only debit or credit cards.
