My limited experience is with a regionally big company here in the NW.
A woman called her daughter who is a customer of mine. The mother is an elderly lady with health problems. She became scared because this company's salesman told her she needed wind thinning, deadwooding, canopy raising, and balancing, just like there flyer indicated people need for healthy and safe trees over her home.
My client called me to ask for an eval on her mom's trees. They were fine. the could have used a little bit of pruning, but nothing was a red flag.
Seems like big company's systematic greed taking advantage of an elderly lady, alone, at home, recovering from surgery.
From an aerial rescue seminar with STARRS, hearing some of said companies employees talk about their work situation, sounds like chew up treeman and spit them out when they are not able to produce up to quota, with slimy salesmen.
I feel like I have gained more trust in my community by this interaction, and so I benefited a bit from their greed by my willingness to pass on bidding on unnecessary work.
