Self checkout at Walmart on Union is becoming a nightmare, I'm old and have a caregiver, now we share a cart as I'm not able to push my own. Everytime they tell us you have to have 2 carts for 2 people as we combine our purchases. Now we're told the manager wants it that way....WHY??? You're causing more congestion at the checkout, besides the frustration of said checkout. I remember going to Walmart with no hassles, go in buy and leave, now you get angry employees, angry customers, and no longer a pleasure to shop. Hey Walmart get it together or lose a lot of business. Because you lost mine.
