It got to the point where I can't even stand to go into a Wal-Mart and I never go there anymore but today I had my propane tank from my gas grill in my car because I ran out and needed to swap it out. I had to go to Staples to get some supplies and its in the same shopping center as Walmart and since it was early about 9 am there was almost nobody at Wal-Mart so I decided to just swap the tank out at Wal-Mart. I went into the lawn and garden center and paid the lady at the register for the swap out. There was nobody else in the department so she grabbed some keys and went out with me. She opened up one of these cages where they keep the propane tanks. She said I don't know if there are any new ones in here but then said there's one more on the bottom shelf in back. So she pulls the empty tank out that is in front of the full one and turns to me and says you're going to have to get down there and get the new one out. Right away I'm thinking that's your job and was about to say something but I decided I would get it out so I could get out of that place. After I pulled it out she still stands there looking at me like I should put the empty one she pulled out back and also the empty one I brought. I just took my new tank and walked off. That is such poor customer service that I can't imagine anyone even operating like that. There are lazy people everywhere but to allow that kind of stuff to go on is just a reflection of how poor the management of this company is. Do they think people want to return after being treated like that? I don't go to Wal-Mart anymore and that is the last time I even think of exchanging my propane tank there. A horribly run business with horrible workers that they let get away with that kind of stuff.
