have had this one customer for 2 years now and for 2 years he has been a PAIN IN THE A**, Usually I pretend that i don't see him when he comes out to gripe, I mean he is so picky it makes me sick! every single time i cut the grass he comes out and finds something wrong with the way im cutting or he always tries to get me to do stuff for free. He always switches the days i cane come and so forth. Well, I couldn't afford to drop him until this year. Anywayze i was servicing his lawn the other day and whyle trimming some hedges near his sprinkler system, i cut part of the main vale or something and water started streaming out of it. So i turned the water off and acted as nothing happend. I really am going to drop this guy very soon! is now the perfect timing? it will probably cost around $20 for the part plus 30min of my labor to fix. it has been raining slightly and i dont think he'll need the sprinklers for at least 2 months or so. What should i do?
