Stop & Shop review: customer service at self checkout

I went in to purchase two items. I also bought a third. 10lb Ice
Lactose Free 2% milk, and I also bought bird food.
I used the wand customer code off the card [protected] 9
When I went to check out for what seemed like the fourth time in the last two months, the machine requested an audit. What I thought was why a person with three items totaling 20 bucks would trigger an audit surprised me, I don't know, but so be it. When the person came to me, she said I did not scan the lactose milk, although it showed on the screen. She took it out of the bag, did her magic, and I paid and went home.
I am now at the point where your store on the post road in Fairfield, CT, "the Circle," I refuse to shop ever again. My wife has long since come to this conclusion, but it now becomes clear to me that your store is poorly run and does not, at this juncture, seem to care about the customer.

Some background I was in the retail business for 45 years, of which many were in the grocery side. I consult, and my consultation for you is that you get a manager to be at the front end and constantly checking why and how the audits are completed. I would also give a class to each of the associates who work the self-checkout on how to handle issues. They are ill-prepared. I love the fact that your store hires local people, and I love the location, but the store is hard to shop in and, in my opinion, badly run. Currently, I would not recommend shopping at this particular S and S
