I think the way Alan runs it is doable, I also think there's nothing to lose and the hire machine could also be my spotting machine.... I can't see it getting so busy that my business would suffer and if it did, I just apply the breaks a little bit.
I can see the scenario now, hire machine for a small job needed but I say to custy, for another £10-£15 I can do it for you, professionally
It'd be the last resort to hire the machine out if I knew the customer was "Getting away" so to speak and falling for the "Splash And dash" C/C....
