I have a lady that I mow for that has actually really helped me put more cash in my pocket by referring me to others she knows. Her lawn really is the nicest lawn that I do as far as looks go. She has referred me for vacation mows, fertilizing and also weekly mows. She doesn't seem to want anything in return. Of course I thanked her after every referral but I am not sure if I should do more. I was thinking of a gift certificate to a restaurant or a fruit basket as she just talked me up to 2 more people on her block resulting in a new fert job and a new weekly mowing and fert account worth about a grand. Do you folks give anything for very good referrals? Let me know.
