Furry Fright

I didn't take a lot of notice when the lady got into the back of the taxi and asked to go into town. On the way she asked me to pull up outside a post office and wait whilst she did an errand. 
 After about five minutes or so I was just sat there bored and daydreaming, when suddenly out of the corner of my eye I spotted something small and furry making its way quickly from in between the seats straight towards me. 
I was out of the taxi quicker than a Danish cartoonist leaving a mosque. 
I thought that maybe a rat or squirrel must have gotten in somehow.  After a minute or two of taking deep breaths I still wasn't prepared to get back in the cab to fight the furry intruder and was stood peering anxiously through the windows trying to spot it again. 
Just at that moment the lady walked out of the post office and up to the car and seeing my shocked expression guessed exactly what had happened.
Sorry she said “I should have told you I had my miniature Yorkshire terrier in my pocket and thought it would be ok to leave her in the car”.
