A woman enters the communal kitchen and goes about making herself a cup of coffee.

Clearly not liking it black, she then gets milk from the fridge and pours it into the cup, giving it a good old stir.

So far, so normal – right?

What comes next, however, is not what you usually expect from your co-workers.

The woman lifts up her dress, pulls back her bra and starts to carefull squeeze out her own breast milk into the shared milk carton.

She does this a few times before putting the milk back, pulling her dress back down and going about her day.

There is no explanation as to why she did this but it could have been an attempt to hide the fact she took milk that didn't belong to her or perhaps she just doesn't like the people she works with.

Of course, it could also have been her own milk carton, but whatever the reason, we'll take our coffee black on this occasion.
