ATM

ATM interactions are pretty funny to me.  When you go and see strangers there, it is very clear that the people using the ATM should try and avoid eachother and mind their own business as they take out cash.  The problem exists when two or more people go to the ATM together.  What should you do while your friend is using the machine?  It seems that it would be a good idea to try and give your friend their privacy, making it obvious that you are making an effort to make sure you do not see their pin number.  Maybe look at the sky, and pace around in circles for a minute seems appropriate.  Who would actually try and steal their friends pin number?  And what would you do with it?  Steal their card and take it to the machine?  What kind of friend is that?  I dont know where I am going with this so ill stop now.
