This is my first season and I have already fired a customer. I went to cut her yard the other day. The turf was about 4" tall. I make a turn and see her standing in my path about 20 yards ahead of me. I stop, shut the machine off and she starts out with "It's only April 9th. Don't you think you jumped the gun?" "I am a retired school teacher and I didn't budget for any lawn care this month. I don't think it needs mowed yet." I am fuming at this point. She continues... "The last service cut it for me every 10-14 days." I explain to her that it is hard on the turf and the equipment to let it go that long. I told her my service operates on a weekly schedule. She says that she will check with the neighbor boy to see if he will do it. I reply with "That sounds like a good idea." The professional I am, I finished the job. When I was done I went to her door, told her that I would not be able to meet her schedule demand and that was that.
