Not as egregious as some, but at least it doesn't involve body fluids.
I had a new employee, first-real-job-after-college, take me aside and discretely ask how the annual Christmas bonus to all employees was distributed. I had to explain ot her that that kind of Christmas bonus was usually a way to share the business profits with employees, and that, since we were a government agency, taxpayers would not exactly be thrilled with us making a profit, much less handing over tax dollars to staff. So, no bonus.
She was only familiar with the kind of large corporations that handed out annual bonuses and it never occurred to her that it was not a universal practice, or that it was tied to company profits.
At least she figured out why the office did not treat employees to a lavish annual holiday party. At that agency, more than one newbie (usually student interns) couldn't believe that any holiday party would be paid for by employees and would be on their own time.
