I stopped going to the potrero safeway for awhile because it was so difficult to get a shopping cart there. I also have cut back on shopping at safeway because shit's expensive. But I went there a few times recently, and there are ample shopping carts. Shopping carts in the parking lot, and in the store! In the past, I would get so frustrated going there and having multiple people hunting for a cart, or being escorted out to my car by an employee so the cart would get promptly returned. I used to drive down to Excelsior safeway a few times because I knew they had shopping carts.
