I do have enough knowledge about hydraulics, and I have learned this over time, and experience. I hope you are honest in your business dealings with educated and uneducated people. Knowledge is power, but it must be shared to earned a good reputation. Having been in many hydraulic shops, I do know that sales people do not give you many options. Most times, in a cash transaction at the counter, you do not know the price until he walks up and hands you the hose or what ever. Most times they do not volunteer the price before making up the hose.
I have read your post, and you seem to be knowledgeable in your trade. I appreciate the advise and knowledge that you
share.
You should understand though that most of the retires are living on a fixed income, and we do worry about pricing. We want value for our money, and not something that will last another 100 years. A $10 dollar hose will probably work just fine.
Business customers usually charge it to their company, and the guy picking up the items probably doesn't care what it cost.
I know, Business is business
