How to avoid the chuggers/cadgers

There is nothing worse when you have things to do and places to be on a busy work day to be accosted by some person saying in an overtly chirping voice and sounding slightly brainwashed "Hi I'm Anita, do you know what some group are doing to the elephants in Asia?" and if you answer no, they rattle off into a very long explanation of what they claim is happening (sometimes inaccurate) to these elephants and usually they do it in such a way to guilt trip YOU into giving them money (which I think goes toward administration costs more so than any cause they've guilt tripped you about)

So here's my guide into avoiding chuggers/cadgers:

• Pretend to be on your phone arranging an appointment or holding a rather tense phone conversation about work. (I pretended recently to be talking to somebody about getting my boyfriend a penis enlargement appointment)
• Music is handy. Look as though you are away with the music. They will not bug you if you have earphones in and you are listening to music.
• If they are one side of the street. Walk the other side. I realize this piece of advice is no use if your business is on the same side of the street as the chuggers/cadgers.
• Avoid making eye contact with them. That gives them the sign that you are keen and eager to talk turkey with them.
• Constantly check your watch or phone and look extremely annoyed and impatient.
