I have a university degree , 4 post graduate diplomas and fix mowers now for a living and am happy to do so.
Now I spend a lot of time with my customers which is why I have a lot of customers .
Some are functionally illeterate so I have taken the time to show them how to use their equipment properly and clean & maintain them.
The stuff they have is totally wrong for the work thay are doing and it was the brand name mower shop that ripped them off, flogging them $ 35,000 worth of gear that they did not need to maintain pensioners yards in residential suburbs on terms that they can not afford to repay.
As for office workers, almost every one who is a manager has a fundamental ego problem with reading instructions.
They are a manager, they control multi million dollar budgets or run big offices so how hard can it be to run a lawnmower.
Any idea how many batteries I sell because these "smart" people run their engines a 1/2 speed to "save the engine" so the batteries never fully recharge.
Or on the other hand how hard it is to sell them a set of blades because the mower is still cuting the grass good so the blades are good & I am just trying to load the bill.
Even after I tip over the mower, put a new one over theirs to show them how badly worn the blades are or take them around to the graveyard and show them all the blown decks, they still won't do it. And even worse are the really smart ones who run with unbalanced blades then try to make a warrantee claim against me when the mower throws a rod or bearing.
Life would be a lot simpler if all my customers had IQ's less than 100 or were blue collar workers .
No small shop rips off their customers , hat is the domin of big brand name shops & big box stores.
Our customers are our reputation, our advertising & our livelihood.
