I went to buy a blade for my electric lawn mower which was available at the Greentree store in Pittsburgh, their web page stated they had 5 left for my specific model. Once in the store, no one of the employees said hello nor "how may I help you". I decided to walk around to find the blade. When I could not find it, I decided to ask the cashier who did not greet me, did not talk to me and instead, he pointed to the isle where the blades were. Yet, I could not find them. I went back to the cashier, and at this point a person called Sharon, asked me what I needed. I said I needed a blade. She started walking to the same isle I was directed before by the previous cashier, she did not say follow me, or I can show you where they are, anything. Once we arrived to the blades, I told her what was the model of the blade, she sighed in a very rude way. I asked to leave, that I didn't need somebody unwilling to help. She stated they were very busy and had a lot of things to do. That is not my problem, the customer deserves respect and attention.
