Dulux Paints

I am in process of prepping my house for sale and wanted to add a fresh coat of neutral paint. I knew I had a discount with Dulux via CAA, so I went to the store in the Hydrostone as it was the closest one I could think of.
My boyfriend and I were discussing colors and a client service rep approached us and asked if we were ready to chose a paint color. I indicated we were still looking at colors and trying to determine the right fit and that once we were ready we would come and see her, with which she carried on her way. Once we had decided on a couple of colors, we asked her to mix up a batch while we decided on the next room. Once she finished mixing, she asked us if that would be everything and if we were ready to pay. I had responded that as mentioned previously, we were still trying to determine the next set of colors.
Once we had determined the next set of colors we asked for advice on the type of paint we should use, indicating that we wanted something that had good coverage without a need to prime, based on the colors that we’re painting over. She referred us directly to the 70 $ paint which I wasn’t willing to spend the money on — once I indicated my aversion to spending that kind of money on paint, she essentially dismissed us and told us to let her know once we figured ourselves out. I had to ask her about certain products that she had on the floor and she was vague and dismissive of anything else. She was the most unhelpful person I have ever met. She made us feel like she had better things to do, and that we were competely wasting her time. As I listended to the other guys in the store help their clients, offering helpful advice and guidance, I couldn’t believe they allowed this person to work in their store.
Unfortunately, I will never return to this store.
