I just left here and I'm pretty upset. I've never had bad service in here, workers are usually…read morefriendly and helpful. Today however there was a girl I've never seen before working. I asked about when a specific cart would be stocked again and she said, "I don't know" so I took a quick look and got a different cart, I could only see through the glass as she hadn't opened it. So she grabbed the cart and I met her up at the register. She gave me my total, I paid, she handed me the cart, only it wasn't a cart, it was a disposable, I've had a bad experience with the disposable once, the battery completely went out on me and I still had half liquid left.So when I realized what it was I asked, "Is this a disposable?" She said,"Yes, you can recharge it", I explained that I thought I was getting a cart and why I didn't want this and again she said, "You can recharge it" I told her I understood that but the last one I got wouldn't hold a charge, again, she said, "It can be recharged", she treated me like a child, I'm in my 40's, I get how things work and don't need to be talked to condescendingly, I asked for the receipt, instead of giving me a receipt she says, "we don't do refunds per FDA guidelines, it can only be used once." So I said, "Okay then can I exchange it for a cart or return it right now?" She said, "Nope, you already paid for it." Wow, I literally just paid, I didn't leave the store and come back, I didn't open it. She still refused to give me a receipt. Rather than causing a scene (because there was another customer at the time) I left. I will be calling sometime tomorrow, if I get her I will continue to keep calling until I reach someone who is above her. If this is how you treat customers I will start going back to the hippy house, they gladly take returns if you're not happy with it, even if it was used. It's worth the extra distance.
