Unwanted advice about fundraising and those ubiquitous yard signs

So I went to a campaign function for a candidate I support but whose campaign I don't work on.  A friend from the hood. Who she is and what race she is in are not relevant to this story. A well known local personage was there to help boost her campaign. The personage was to speak, and introduce the candidate. In the back of the room, her campaign manager had just finished boasting to a supporter that this campaign was the "first to have yard signs up," when the short speechifying started.

As soon as the candidate finished her brief remarks, thanking people for coming and reminding them to tell their friends to vote and please take a yard sign, people went back to the refreshments and the very nice complimentary wine.

I was standing next to the campaign manager, an earnest young woman with little experience and, from what I had seen so far in this campaign, no overwhelming sense of the urgency necessary to bring a campaign to victory. ( I got a clue about that the first time the candidate's spouse called me for information the manager should have been supplying.)

"Isn't someone doing a money pitch?" I asked somewhat incredulously. (Campaign101  -  always ask for money.)

"That's not how we do it," she replied. "Everyone one here already donated."

"Yes, that is how we do it" I couldn't help responding possibly a little snarkily

With that, and before I could get to the part about people who've already given being the most likely to give again, she turned her back on me and stomped across the room.

Campaign folk can be touchy, I thought. Besides, she has to get rid of all those yard signs she's squandered the campaign coffers on.
