I picked up a customer after they cut once this year. talked to wife,husband away most of time. He calls and tells me lawn had never looked so good. (done 8 times)Says he'll pay me to do his fathers.I talk to father and do the job.He says great job,But it's his property he'll pay me. I take the check.The next day I'am at the sons'. I tell wife I'am going to raise cutting from 3 to 31/2'' and why. She says good idea. I'am ready to leave and the husband pulls up. Thinking I just got there he says great job,but can you cut at 2''. I say no and explain why. I tell him his father paid me and they should decide who'll pay, don't put me in middle.This week i show up and both places have been cut. No one home. I do a great job but get fired from 2 places? Where did I go Wrong? Sorry this is so long needed to vent.
