I have a street with many customers 1/4 acre lots they all talk to each other. On the 3rd cut of the season one asks to be cut every 2 wks and knows she will pay a little more. I tell her a lot more and she says ok. Little does she know I have a plan to replace her or get her back in to compliance with the rest of the street. I get lucky and a guy one the street over asks me to cut his lawn . I like to get a replacement before I get too cocky with them. I let him know my program and he is happy to get on board. On the day of the 2nd week Lady's cut I remark how high the lawn is and remind her of the higher cost (although not double $). I purposely leave the grass lay and it looks like sh%$. She hands me payment and I tell her that I can't cut her lawn any longer as I am unable to do a 2wk cut and get good results without bagging and that would cost as much as 2 times a regular weekly cut. She says she understands and will ask her husband to get it cut weekly. I remind her HE can cut it but I 'm out for every 2 weeks. The bottom line is if I cut her every 2wks and make it look good the rest of the street will want that program too. we'll se if the hubby gets back with the program but at least I replaced them if not. Dealing with customers is a game and you have to play to win!!!
