As a traffic safety consultant, I often gave talks to organizations on accident prevention. One night after I spoke to a PTA group, the program chairperson thanked me profusely and gave me a check for fifty dollars.
"Giving these presentations is part of my job," I said. "Could I donate the money to one of your causes?"
"That would be wonderful," she gushed. "We have just the program that could use it. We're trying to raise money so we can afford better speakers."
