See my reply to Old Bald Guy.

Basic D rats: chocolate, hard candy, high energy/sugar types.

Basic K rats: US mil aviation dining packets, includes: plastic knife, fork, spoon, sugar, salt, pepper, drinking straw, napkin (can be used for TP), church key, etc. Many commercial varieties are available as you will receive them from caterers @ different events with some more or less of these items. Throw in 4 cigarettes, matches, and 2 pieces of Chicklets and what do you have? That's why I save the packaged sporks, packaged dining kits from take-out dinners, packs of ketchup, taco sauce, salt & pepper packs, etc as I come across extras.

It's because I am a cheap date with a tight fisted technique with money.
