Stan, I take that point on board. However, you have to balance things. Are you prepared to be p*ssed around by some custies to try to stop competition? If you are in business, you should welcome competition. Let someone undercut you, then go after better paying work. Or take the crap and not really know what you are going to earn this week
A lot depends on what rounds you have of course and if it's a case of humouring one customer so as not to rock the boat, yes.
