Nerf the corners

Today at work I ran into a colleague coming round a corner while holding a cup of coffee. Coffee disaster ensued. And once again I remind myself: Do. Not. Run. Around. Corners.

Just peek a little. How hard could it be?

EDIT: Geefat just pointed out to me, that the peeking tactic would cause other people some concern if applied out in the streets of Stockholm. I don't know. You still need to keep the coffee stain ratio on a reasonable level.
