It's just that simple! When you don't except "NO", 1 of 2 things things happen.
Here is an example. Yesterday, I needed to figure out why my clothes washer was not taking in hot water. Since, I can get behind my washer without to much effort, I had a YouTube video telling my DIY self to start by checking the hot water inlet. I went to turn off the hot water supply from behind the washer. As I turned the knob, it fall off it my hand. It was missing the nut. So not knowing the size of the nut, I put my phone under the stem and took a picture of the complete cold water side. With knob, washer and phone with photo, I headed to my local Ace Hardware. I love Ace because they usually have very helpful staff and 2 walls of nuts, bolts, washers and stuff I can't even explain and the best part is, I can buy just the quantity I need.
As I walked in, I was greeted with a, "How may I help you?" As I was walking to the "2 walls of stuff", I told the guy just what I needed. I showed him the washer, knob and the picture I had bought along. The guy looked at me as if I was speaking a foreign language. He said that he had no ideal how to help me with what I had bought in. He asked where the whole knob assemble was. I told him it was at home attached to the pipe from the wall, where it belonged. Next was a very short speech about how he wasn't going to be able to help me. I told him thank you, I would find it myself. The Ace guy said he didn't know how. I quickly explained that NO was not an option, that with 2 walls of "shit", there had to be something and I was going to find it. I said thank you, goodbye. He said he was not trying to be dismissive, but without the threading on the valve stem, he was at a loss. I said, I need a nut, so let me get to finding one that would work. The guy left and I begin to open the tiny drawers of nuts and other stuff. Next thing I see is the Ace guy coming back with the whole assembly he asked me about in which was partly at home...attached to the pipe. The Ace guy take the thing apart and measures the nut from the stem, to get the size of the nut I needed. 1/4-28...and I had 1/4-20 in my hand. I told the Ace guy, "See what happens when you don't accept NO!" He stepped up or I would have figured it out. They were 25 cents each. I bought both as to my eyes they looked the same. I got home, put one on to hold the knob and I was able to turn the water completely off, which was my original objection.
So the moral to all of this is...If you don't accept NO, shit gets done! It is apart of my mission statement. "Define your "NO" to get to your "YES". In this case, the Ace guy either was motivated by my no quit attitude, he did not want to be out done, or he felt bad for me. In either case, I got the nut I needed!
