Squashed tea

When I arrived at the incident last night I chucked my work bag into the truck and started to get briefed by Austen. Thankful the incident was nearly finished and we were soon on the way back to the station for a de brief.
Back at the station I asked where my bag was and some kind person shouted its ok its in the truck....... I recovered my bag from the back seat and discovered that my tea.....a Cornish Pasty was now the size of a sausage roll......

So come on who sat on it please?
