for me, if it's not a valid, proper reason, they're in the bin.
I spent too much time in the past pandering to pain in the a**e custies
if it's a particularly well priced job I might put up with a couple of times
also, if you don't take on new custies and drop crap ones, how do you move your business forwards?
a once a year price increase? each to their own, if I was still working like that i'd still be stuck working on the council estate I first built my round on before I knew any better
that sounded less controversial in my head!
