Yes, literally this, but without the smug.
Have you ever set lenient guidelines, people took advantage of them in a way you didn't like, so you were forced to tighten your guidelines in a way you didn't originally want to?
eg: a professor establishes a generous late homework policy, which most students use reasonably, except a few who decide to turn in everthing on the last day of the term and make the TA's lives hell. Prof is allowed to be disappointed and then adjust their future terms' policies to be more specific (eg "submit assignments max 5 days late").
