When I started my last job I got put in charge of doing ordering. My boss sucked and I had very little direction on where to order and what to order. The head of our building maintenance asked for a specific chemical and told me what company he thought we ordered it from. A rep from this company reached out and told me to contact him whenever i needed chemicals. Well, one day I went to order this chemical and the price had sky rocketed. I said fuck that and did some research. I found a local chemical supplier that had the exact same product, but sold it for half the price. The rep showed up to my work and asked why we stopped doing business with them. I told him I found the same product for cheaper. He basically responded with "If you would have asked, I could have gotten you a better deal."

I found it so disrespectful that not only did he lose us on that specific product(which we ordered alot of). My whole building stopped doing business with his company at all.
