That article caused a memory flashback.
I remember the cafeteria tents as a kid. Crowded and hot. Straw on the ground. Tables made from plywood and 2x4s. You had to stand to eat. Get em in and get em out. Table too tall for kids. I couldn't reach my plate....no, it was a tray. Metal trays sorta like they use in the army. Uncooked scrambled eggs. Apple juice or water, no soda.
Later they changed to prepackaged food just handed out at tables. They wouldn't use the concession stands as that was part of the "world" so they just put a table in front of the concession stand and had styrofoam coolers full of sandwichs, etc. Then they quit using money and change to WT script. You had to buy the script at booths at the entrance and then use the script to buy food.
Then even later, after the Swaggart deal, they started giving food away on a "donation" arrangement. That didn't last long. After that, food was done away with altogether. They asked people to bring light lunches. Some people always went out to lunch even though there were some half-hearted attempts to discourage them.
The latest change is that they really are putting pressure on the friends to not eat out at lunch during the convention. The colisuem concession people see all these JWs hoofing it to MickyDs after the WTS told them that concessions would not be required and they wonder how much money they are losing. So the WTS really tries to keep the R&F in line by highly discouraging them from eating out.
How the times have changed.
