Is it unprofessional to ask a customer about the previous company that took car of his lawn? Example: I just put an estimate on a full maintenance lawn because the home owner was unhappy with his guy because he rutted up his yard pretty bad and seems that you can see everywhere he turns. I wanted to ask who it was but I didnt for the fear of being unprofessional. I also have asked a few people what they were paying their previous company. What do you guys think?
