We have a lunchroom for a reason. Smelling someone's curry or fish while you're trying to work fucking sucks.

Having to use a greasy mouse and keyboard because Samantha was "too busy" to spend 15 minutes eating her potato chips in the lunch room drives me up the wall too.

Thankfully it doesn't happen as often where I currently work. I've also started making fun of people who do this, in hopes that they'll feel embarrassed enough to not to turn it into a habit.
