Hello H.,
That is why I now charge an "evaluation fee" up front before I will even begin inspecting or testing anything. I got tired of the "I just paid someone else" or "I don't have any money" stories.
The worst ones are, "I will pay you when I get my check". They never seem to get paid so they can pay me.
Sorry, it's just business and my knowledge, tools and years of experience did not come free to me.
I work strictly by personal references these days and most customers already know ahead of time that my time is not free.
This approach culls out the pretenders and self-proclaimed poverty cases most of the time and it makes it clear to the ones that think they are a "privileged customer" think twice.
I am not swamped with deadbeat "free" work now, thankfully, but I keep steady and get paid as I go.
Any good experienced small engine or ATV mechanic in my area is rare and most of the dealer shops are only hiring breathing bodies with no experience and very poor reading comprehension skills. All of the independent shops have basically closed down. All that is left are the retired mechanics or disabled vet types like me who still want to be active.
For the few that have tried to do the "leave a note", then drop off equipment and run on me, I just stack them up out back and wait for a phone call. Thay have to come back for their equipment or play by my rules.
If they pay for an evaluation, I evaluate the problems, work up and estimate and have them pay for the recommended parts before I proceed further. They need to spend their money, not mine. They are much more attentive when they have their money (skin) in the game.
I quit doing exploratory teardowns just to satisfy a customer's curiosity, then they bail on me and stick me with their torn down junk.
The old days of the blind drop off and "call me when it's ready", and I will settle up with you then are gone.
Did I lose some "customers"? Only the self-entitled ones I could stand to lose anyway.
