I have a commercial customer with 3 businesses on annual contract. (cut, trim, fertilize turf and blow parking lot) I started doing little extras for no charge in my effort to enhance "customer service". i.e. trimming back limbs, spraying weeds in parking lot cracks, and light pruning or some overgrown shrubs, but nothing major. Today I got a complaint that the hedges ( and there's a lot of them) have not been trimmed and does not look up to par with other like businesses (Doctor's offices). Since I am basically at the end of the cutting season and looking forward to a couple or three months of payments with little work, (hey, I made it up this last summer) I told him I'd prune the shrubs since I didn't want him to tell me to basically take a hike at this late date. I am debating whether or not to attach an additional charge but I basically agreed to do the job, in his mind at least, for no additional fee. Is there anyway to correct how I have obviously mishandled the situation? I hate to remain stuck with what is proving to be a change order in the contract with no additional money.
