Let me start by saying yes, I hold grudges for centuries and will some day seek therapy...
Every year we (NYC Backers) promote our tailgate at the Meadowlands on the boards. Every year Sue bashes us as being unorganized because when she came one time, she had nowhere to put her bowl of pasta salad that she made.
We get close to (or maybe over) 200 people there. We can't organize every itty bitty detail. We leave stuff like that up to people who attend - to work together, share grill space, table space, etc.
