i have a customer, that i do grasscutting for, minor spring and fall cleanup(no trees), and this year he wanted me to do his snow. we did. he always comes out and pays on the spot. the last time we had snow(back in january) he called, he said he would be going to connecticut for a week, but if it snowed, please do the driveway and walkways, and he will pay when he gets home. fine. it snowed. we did the work. didn't bill him or hear from him, no big deal. so, yesterday i'm doing a cleanup for his neighbor, and he comes over and hands me $30(his standard fee for blowing out one bed, and running over lawn with mower), i said thank you, and you still owe me $40 for the last snow. he says you didn't come. i said i certainly did. he said why was there snow all over when i got home. i said you were gone for a week, the wind blew the snow around, but didn't you notice the piles on the sides? how do you think they got there? he insists i didn't do the snow. i said whatever, i got $30 here, you owe me $10 more, when you cough it up we will talk about the spring cleanup. he gets mad, demands his $30 back. i say nope, give me $10. he says he's gonna call the police, i said go ahead, if i'm lucky, they'll shoot me, and i won't have to deal with your cr@p anymore. he storms in the house. NOW, tell me almighty lawnboys, what did i do wrong here? and what would you have done differently?
