@FBM,
Yeah, some are really smart.
Personally, I do #13 and #19 all the time.
I always cook or heat something for :22, :33.....1:11, etc. much too much work to move finger.
I buy cases of 500 of 9"paper plates made from sugar cane fiber from Amazon. They are really sturdy, are compostable and cost like a dime each. I'll reuse them if I'm eating something non-messy like a sandwich. They also make a great makeshift cutting board. Takes me about a year to go through a case.
If I bring food home in a to-go container, I'll rip off the lid and use it to eat something else off of later. Coffee filters make great bowls to hold snacks like crackers or nuts.
Oh! and I also buy a case of 1000 of 12 oz starbucks cups. You can get them from many suppliers. I use it for my coffee or ice tea, and since I take them black w/ no sugar, I can just rinse it out and use each a number of times. I actually go ahead and sell a few sleeves of them on ebay for a good profit, and so the cups I keep are free.
