A No Guilt Signal

I hate it when my government run liquor store asks me to donate.

But how can I say no at checkout with a line full of people staring at me?  When I hear someone in front of me say no, I get a little taller but usually cave when its my turn.

There should be some sort of "NO" signal to the cashier.  A yawn, scratching of the head or pretending to be on the phone.  Oh wait, the phone thing won't work because there is always some yahoo in front of me on the phone.

The best no would be for the government run retail store just not ask.  I donate every day when I buy something: its called taxes!  You use the taxes and donate.

And if I wanted any more guilt, I wouldn't call my mother for a day.
