Some recycling bins have appeared in the coffee lounge - one for plastic and for for paper. However, the signs directing you were identical save for the small font saying "PAPER" or "PLASTIC" in barely readable black on green.
I've taken a stand and gone all arts and crafts.
It's a victory for intelligibility. And I've managed to cover over all the Comic Sans. And yes, I did recycle the half cups.
If that's still ineffective, there's always one last resort.
