I’ve never had it done, but from what I’ve heard they charge way too much for what it is…
Ha ha, Eldo, you reminded me of an old joke.
Foreman has one of his production machines down, so he calls the repairman. Repairman comes in, looks at the machine, strokes his chin, takes out his hammer, bangs on the side of the machine, and it starts up, everything working as normal. Foreman is ecstatic to have the machine running, repairman hands him a bill for $500. The foreman is outraged, he sputters at the repairman, "would you care to itemize that bill?" Repairman takes it back, writes: Banging on side of machine: $1; Knowing where to bang: $499.
PS I realize that to get that joke you have to imagine an old-time world where there were factories with production machines and foremen, here in the US.
This reminds me of a long-term customer I had once -
(For added context, this is 2020 during the height of the pandemic, and a normally active old man being forced to stay at home due to lockdowns, so he had a lot more time on his hands.)
This person, one of the richest men in the country, standing outside his brand-new mansion with the hand applied gold leaf on the pillars of the front entrance and ancient Greek goddess statues, told me that I charge him too much...............after working for him and his extended family for near 15 years. (I was not by the way, he got the same price everyone else did, below industry average too.) Well, I explained that you are not just paying for me to cut the grass, but also the horticultural knowledge that I have. His snarky reply was that
"it's not rocket science!".
I found that statement hugely offensive, a complete disregard for all I had learned over a 20-year period. Horticulture is not something you learn about overnight, it takes decades to learn, mostly from hands on experience. It's not just digging holes and cutting grass. You basically become a plant doctor, knowing how identify and treat certain pests and diseases, becoming a plant nutritionist, know how plants function/biologist, learn how are where to prune, learning about soil and become a soil chemist, becoming proficient in plumbing and electronic watering systems, be a small engine mechanic to maintain equipment...................................... So, I might be just a dumb gardener, but there is more to it than he was crediting me for.
A few months later, I resigned after reaching the end of my tether. But guess who was ringing me to help diagnose the bug infestation on his rose bushes? Well, apparently, it's not rocket science, so you figure it out!
There are two things I learnt from all this -
1. NEVER question a person's worth, you have no idea what it takes to do one's job and the price asked for it.
2. NEVER compromise on what you think you are worth, otherwise, what the point?
lol.
