My residential customer lawn was 11 days uncut and grass was high. I have a customer who has chosen to handle his lack of service by threatening to make my name mud in the Home Owners Association Board, ask for his money back and approach me with a side arm trigger unlocked during discussions. First email I received: "Service is needed pretty bad on my lawn. Please complete that by Tuesday. You never came back to do my hill in the back and it now stands over 1 foot tall. To tell you the truth I was a little embarrassed to tell my friend yesterday that I pay a lawn service to take care of my yard. Considering you live right down the street I didn't think I'd have to ask you to service my lawn every time." i responded by saying " It seems that I have too much to do to provide quality service for your yard. I mow lawns on the weekends as a method of gaining extra income. This is what I will do for you as a service. I will mow, trim edge and blow ASAP. Then I will return to my desk and make some decisions. " THEN he responded by email "Considering I pre-pay you for a service, that doesn't get done, I'd either like the service performed as agreed upon or I want my money back and services terminated. Your poor business performance will be noted on our HOA web site, and spread around the neighborhood by word of mouth as well. I know you just do this for extra income... but that's no excuse for taking customers money in advance, then complaining that you have too much to do to perform the service. Maybe you should try something else for extra income." When I went to his house he had a side arm at the ready...SHOULD I DUMP THIS GUY? or handle it professionally and continue service?
