Hey guys
Im really referring to when a spec asks you to do something you cant do, or maybe you can but wont.
Im referring to the bill switch Ive been doing a lot lately. One woman, after changing her £5 to a tenner, she inspected it then put it back in her pocket and said Thanks before trying to walk off

The one I use now is, after changing £5 to a tenner or £20.. to say '' And as much as Id love you to keep this, one of the magicians codes states that we are only allowed to defy the laws of physics for entertainment purposes and not for financial gain, unless the financial gain is for the magi.. therefore, while I have the ability to change your £5 into a higher amount, I am unable to let you keep it, though I would be keeping within the code to keep it myself

What do you guys use? Have you come accross spectators that ask to keep the higher note and are serious about it?
And while we are on it.. any other examples of responses to outrageous requests might be entertaining...
