Customer relations- how would you handle this?
for the lights a simple set of bulbs and a couple light switches fix the light issue. just wire in 2 light sockets on a seperate switch. it is easy to do and can be mounted to a simple post.
my normal yards all have a speed limit sign of 3mph because of the radiation detectors. if you go through too fast or dont wait for the light you reweight. you are also directed in person to a suitable unloading spot. (nice if you have a nicer vehicle and want to hand unload to avoid damage. normally if available with customer load they also provide a helper who also monitors content protecting yard.) if you dont follow the simple rules you are refused service.
anything less than $10 in my yards is a donation as they dont cut checks for any less.
as for reputation you made a good faith effort... you cant do more than that. idiots like that are why many in our are seen as distasteful. i agree he probably would not bring you enough to be worth hassle. you did your part and were more than fair.
