A lot has been made in the media about this incident. Some saying that there was an overreaction towards the man concerned, some people saying that such behaviour is unacceptable.
So is goosing ever acceptable and what is the best way to react? Personally I think that goosing isn't really appropriate unless it is between partners. An overreaction? Possibly, but better safe than sorry. At the very least, if meant as a bit of a laugh (which is the usual reason behind it) it should be like other practical jokes. Meant for people you know well who can take it.
