Well she probably could well have done something differently. Namely, probably an entirely different demonstration.
I will level with you for a moment. If I could make a comparison to another cause, I am often sympathetic to the cause of veganism. I am not vegan or vegetarian myself, but I can't deny they often have a point when they argue the ethics of treating animals like commodities.
There's the kind of vegan activism where you chain yourself to a truck full of cows ready to be driven to the slaughterhouse; you make a clear point and photos taken of your arrest as you're dragged away draw attention to the undeniable reality of where your meat is coming from. It might even give a few meat eaters some serious pause; the reality is someone is being arrested so a huge corporation can proceed with a literal slaughter.
And then there's vegan activism where you march into a fast food restaurant, bother innocent minimum wage workers, and spread fake blood everywhere...
In short, even if this woman had a point, she does just look like a bit of a ninny standing in front of a robot and (presumably) some poor fool is sat wondering where the heck his dinner is.
