Walmart AGH!

So I was at Walmart today getting formula (the joys of being a mom). I was by the high chairs and carseats to get out of the area. Well Blake's car seat sits on top of the little basket in the front of the cart so I can't see things in front of me if they're on the floor. I bump into a box that was in the aisle and it knocked something off the shelf. I didn't pick it up cause it's not my job and that box shouldn't have been there in the first place. I saw an employee with a cart, she looked like she was stocking. Then I bump into something else, a step stool that looked as though the employee was using it. So then I stopped a couple feet away to answer a text. The girl got mad I guess cause she was mumbling underneath her breath and walked over there all huffy and picked up the item and shoved it back onto the shelf with an attitude. I was so close to saying something to her but I didn't want to get confrontational with my kids around.
So I headed up to the front to find a manager. I waited for maybe 7 mintues or so and finally someone came. I told her that I didn't pick it up because it shouldn't have been like that in the first place. And for that lady to get an attitude was just uncalled for. I even told the manager, "I don't think I should say I'm sorry for not picking it up because it shouldn't have been on the floor in the first place." and of course she agreed with me and apologized. I saw her walk right over there so hopefully it was taken seriously.
I'm not one to complain about anything but for some reason it really struck a nerve. It's like Un hello? It shouldn't be a mess anyway. AHHH, whatever I just don't like Walmart. The funny thing is I started to like them because they're employees were getting nicer and just more helpful, and then this shit happens. Back to square one, they have to redeem themselves all over again.
