I used to dread these annual Service Meeting items,, when I was Secretary. One of the last ones I did prompted me to write to the Society and make comment about the negative nature of the things I had to say. guess what? I got a very condecending reply.
re Litter - the last D/Assemblies i went to had no litter bins , you had to take your own litter home
Food service can vary locally. I know of one U K assembly venue that insists that the catering comes as part of the hire package and so we could purchase food and drink(at commerecial prices) from "Worldly" stadium staff at any time. But mostly around here it is strictly bring your own.
I know one thing, the assemblies have lost the spirit of fun and comraderie we had when we were young. Oh the joy of scraping leftover food off mealtrays when we were boys! But we had a few laughs....
