Appropriate Response?

One of the things that Anne and Mark occasionally struggle with while visiting countries throughout the world is finding the appropriate responses to various things without knowing local culture.

For example, when a person sees a sign like the one below, we cannot fault him or her rushing up to inspect it and/ or take advantage of the photo opportunity it presents.... or both.

Go Hawks!!!

If in Madrid (Spain) and see a sign for the "Iowa Cafe," any self-respecting Hawkeye alum is required to check it out.  This is clearly the most appropriate response.

But what happens when the appropriate response is not at all clear?

Chaos. That's what....

Case in point - what is this?  Is that guy climbing through the window with a pick axe?  At what point in human history - seriously - has the human race profited because a guy grabbed a pick axe or hammer and ripped something up?  And, further, when I see this sign, does that mean I should grab a hammer and start busting stuff up?  Would that be appropriate?

Another example.  If you find yourself at the airport and see the jetway pictured above, you know that it is going to be repaired and probably poses no real danger.  But... you still don't want to see mechanical problems immediately before boarding a plane.  So what is the appropriate response?  A prudent person might take this as a sign and maybe decide to not board a plane at an airport with this sort of thing.  (Anne and Mark boarded a plane that day anyway.)  Appropriate?

Example #3:

So, umm.  What... um...

It kind of looks like ... well...  ok, nevermind.  If anyone can tell me the appropriate response for this one, let me know.
