Meh. None of this is worth getting upset over.
I just saw several flippant comments about it being "just grass" and tones that suggested that charging several weeks worth of cuts was simply "too much".
I don't feel it's too much. Slobs should not be rewarded for taking their good old time getting the grass cut. Pay up.
For me, it's personal since I'm watching my own neighborhood go this way.
Some customers will pay and some will not. I roll the dice and toss out a large figure. If they take it, I'm paid for my efforts. If not, I just carry on with my regular lawns without missing a beat.
