We take care of a H.O.A. (condo) and have done so since 1993. They are generally good people, but I have a problem. Two weeks ago some "thug" approached my Hispanic employee and began yelling at him because we blew debris on his newly washed 1993 4-door Buick with $4,000 rims. This guy drug my "timid" Hispanic employee around the car showing him the dirt that had settled on his newly washed Buick. He then approached my other employee and got in his face, consistently using the "f" word and wanting some type of retribution. My leader told him there was nothing he could do other than blow off the car with the blower, then gave him my business card to give me a call. Well, the guy called me and was rude on the phone, so I hit "auto delete". The next week the same guy ran across the parking lot carrying on again, even though his car was not in the parking lot that day, asking why Kenny's boss was trying to "f" him. He wanted satisfaction. He was within inches of Kenny's face screaming about the situation, at which my leader told him to back off or he was calling 911. When the crew returned, I found out about both incidents in detail. In fact, this is the first time I heard that he had put his hands on my Hispanic employee. It was very upsetting to my Hispanic guy, even though he did not understand everything the guy was telling him, as he speaks little English. Neither of my employees wants to pursue filing charges, so I contacted the H.O.A. (longtime friends) and resigned our services. They did a full investigation and found this guy to be a renter, not an owner. They went to the unit owner and levied a fine against the owner for not controlling his renter, and went to the renter and explained that he would be facing future charges and lawsuits if he acts in a similar manner toward any other residents, visitors, or contractors on the property. My dilemma is the following: This guy is obviously a loose cannon. By the way, he is not a teenager, but a 31 year old man. He is clearly pissed that I did not call him to offer to wash off his Buick. Perhaps I should have, but I cannot control the wind, or the elements of the lawn care industry, nor can I wash every car in every parking lot due to running our blowers. It just seems that I see many people being murdered in less volatile situations on the news everyday. I fear for the safety / comfort of my crew when on the property. I have 24 hours to let the Condo's know if I want to return for future service. What would you do?
