i never heard any such thing or saw any action taken about people going "out" for their refreshments or food.
Well, come to soutwestern ontario, Canada and this is exactly what is done. For the last few years a few months before the Kitchner district convention a letter is read telling the r&f NOT to go out to get their lunch and if they do go out to put it in a generic bag. Apparently the stadium vendors have been raising a fuss because of the business they are losing by being closed during the JW conventions. wanna
