Let a modeller loose in a cafe and what happens?
He doesn't leave the tiny jam pots or used coffee stirrers to be thrown away like any normal person. They go in his rucksack for washing out to be filled with nuts and screws and stuff.
The stirrers will probably be an aid to holding things being soldered, releasing a nice aroma of hot chocolate when they are.
I like to think I'm being "green" rather than hoarding...
