My old foreman told me my coolant mix looked like weak tea and it was killing my tools

He walked over to my machine in the middle of a run, pointed at the sump, and said 'That's not coolant, that's dishwater.' I was mixing it at about 5% because I thought it saved money. After a string of premature insert failures, I bumped it up to the proper 8% concentration he insisted on. The next batch of parts came out with a way better finish and my inserts lasted twice as long. What's the one piece of simple advice that made a huge difference in your shop?

What did your foreman say when he saw the better finish on those parts?

He just grunted and walked off. Did your guy actually admit it was better, or did he try to find something wrong with it? Mine never gives a straight compliment.
