Ha... me too. I'm glad to still be getting film!
WRT "waste" I guess I'm much less worried abou thte possibilities of optimizing waste (maximizing efficiency) only becuase I knw that there is much more waste that happens further up the chain. Although 75% of the fuel in our cars may get wasted... that is a small portion of the waste that occurs during delivery, manufacturing, and mining the raw products that beome gas. Same with film.
