If I'm doing work at the property unrelated to mowing I generally ask if they want an estimate for mowing. However if they say they have a company already and seem happy with them, then that's how I leave it. I dont try to be the guy who comes in 5 bucks cheaper. Its just respect for a company is doing a good job and the fact that I HATE anyone who low balls work! What about you guys? Is "stealing" work just business? The way I look at it, there is only so much business to go around and you need to fight for your share. But where to draw the line. thanks for reading.
