More disgusting than annoying. Colleague brought in a buttercream sponge cake that she made for another colleague's birthday to have at lunchtime - she left it on the work top in the staff kitchen
She went to make a drink and found that someone has lifted the cake box lid and swiped their finger through the buttercream.
