A garden club had rented the house for a meeting/workshop, and I opened the house for them and pointed out where the tables and chairs were, and the finance administrator later pulled out the projector screen for them and the two ladies setting up seemed quite happy. But after the whole thing was over, the one lady who was supposed to help them set up but showed up late complained about how there had been no staff to set up and that it had been agreed that we would do it for them and that the space was too small.
My theory is that, since she dropped the ball, she transferred the blame to us. She even got our ED involved. Meanwhile, all the ladies breaking down and cleaning up were all "we're fine! This was lovely!" while whiny lady is all "we're big donors and we don't think we'll be renting this facility again". When in fact, for their hundred dollar membership, they get one free rental, and if they'd come off the street to rent, they would have needed a membership fee plus several hundred more for the six hours they rented the place. Bite me, garden club lady.
