What an odd figure of speech. I guess a person who is in the market for pants and whose legs are different lengths is a tough customer.

But if a company is meeting your needs -- I mean, if you got your expected burger and beverage with a minimum of agony, there's no need for gratuitous fuss.

Pick your battles with care, since there's a finite number of battles you can attend.

That said, a company's people can get really upset if they can't meet a person's stated needs, if doing so is what they're supposed to do.
