To those recommending the coerced business do a lousy job ... If the fags can prove that the work on their contract was substantially poorer than that on the business's typical work, they can still prove discrimination and sue for even more. Plus, the business wasted all the time and opportunity money taking the job and doing it poorly.
Better to simply say "No" and leave it at that. You don't owe the fags an explanation. And you don't have to lie about it. You just tell them no.
