Janitorial Belt

[Superlagg]

You could also carry around a toolbox. With the galoshes on, you're much less likely to run into something that'll knock you over, which means that there'll be a lot fewer opportunities for someone to steal it. That's what I do on Destiny, just swipe a toolbox, fill it with janitor stuff, and then slap a label on it.

It does make jockeying trash into bags a lot trickier, though.
