"Dinner" always served in the massive tents they set up and cost 65 cents. Some cheap-ass cola as part of the meal. "Tables constructed of pieces of plywood. You stood when you ate. Pioneers ate free. The smell of the steam cleaning they used to clean the trays.
My very first convention memory was at an International assembly, where food was served in the large tents and you stood at makeshift plywood tables. Sawdust on the ground. The smell of bulk cooked food, plywood and sawdust all intermingled together under those huge tents. I was so young, I could not reach the table top, I had to hold my plate and try to negotiate holding it and eating with out spilling on my little boy suit. And then reach up to the table top to get my drink, without spilling it.
It's a memory seared into my mind, and now as we describe those memories, it doesn't sound like we're describing part of a Worldwide Brotherhood meal experience, it sounds more like a refugee camp.
