I have this decent 7-8 year weekly mowing customer. I always get them to prepay. But, they are the nickel & dime you type, that expects to get free extras along the way. Unbeknownced to me, just since my last mow, last week. They decided to have a specialized stone and limestone walkway installed inside the ONLY entrance to their PRIVATE upper back yard. Thus, they have now requested I do not take my zero turn rider down this new walkway anymore. It's the only way to get to the grass area, period. This Path to the grass(now made of "shakey" materials) is about 50 yards long, and 10 feet wide. She thinks I ought to "PUSH" mower this area now. First off, I retired any push mowing, and the mower, after Last year. I finally found another 36" walk behind just for these circumstances and narrow gates. I'm pushing 60, have two bad knees, and generative back disease(I know these things mean nothing to you guys, them, or anyone else. But they do to me.)They realize I'm older than them. They're in their 30's. Both are MD's, and have more money than they can spend. I estimate it will DOUBLE the amount of time that I have to spend there. Again, this walkway was just installed mid-season. No consulting with me on the "newly increased laborious" situation they put me in to service that area with the new pathway constraint. They already prepaid for the season BASED on their EXISTING landscape at the start of the season, with my zero turn rider, and my 36" walk behind being used. Has anyone out there been through a similar situation? How did you handle it? Take into account age, health conditions, desire/need to keep the customer, lack of communication/total disregard by customer, etc. I am looking for suggestions on what to call this "special service" request charge that I am planning to charge them. I have thought of these so far: -Irregular equipment charge -Special service request charge -Accessorial Equipment charge -KMA and get lost(haha) Extra Cost basis: -One price if I have to buy another push mower/use mine. -one price if I borrow their push mower(if they have one). One last important thing: I am looking for suggestions on wording for a disclosure statement(so I'm not liable for potential damage to the new walk), just in case I can talk them into taking my 36" walk behind down this path(without damaging it). Then, I can use it on this area without charging them any extra $$$ out of pocket this season.
