Actually, yes, I have in fact worked in more than one restaurant in my younger days.  The disgusting stuff I watched happening in the kitchen on a regular basis was one of the reasons I didn't continue to do so.  Well, that and the $2 an hour plus tips I earned (yes, it was a long time ago).  But, to address your question here, if making payroll and keeping the doors open comes at the expense of deceptive, evasive, or just plain ol' bad business practices (ie., the restaurateur telling me I am eating a pork chop when its a duck and -knowing- it is a duck, for example) then maybe the restaurateur should find a new line of business that doesn't depend on honesty and forthrightness.  Speaking of which, I hear a bunch of bums that refer to themselves as our "State Representatives" are fixin' to get kicked out of office this fall.  Should be a perfect opportunity for folks with said lack of restaurateur skills to seek new (and probably much more lucrative) employment.
