^^ Ah the early times of losing your first few to "odd" behavior. We have lost a few to the "mower size" problem. Granted, if the mower is too big or too heavy for a property and I have the means to put a smaller mower on it I will, but I will charge a little more for it. We are "professionals" we use commercial equipment. Restaurants don't buy house hold stoves, racecar drivers don't drive a Taurus on the track. When you do it day in and out you need something that can handle it. I won't change out my whole equipment set up to make one customer happy. Also lost a few to timing, it happens. Try to get everything done at reasonable time but you will always get a few that think if you don't get there by 4pm you forgot. Some people think they are the only house we cut lol. Looks like you weeded out a couple headache customers though, the better ones will come, and those are the ones that are worth it. Losing the first few suck though. Remember when I had 25 accounts and lost 2 neighbors because I was underbid $1. Still gets me frosty, but glad I lost them in the long run. Sure some other company came along and shaved $1 again.
