Rushed to the doctors

I was at work today when I observed our older mechanic servicing drum brakes to a Corsa. The shoes and cylinders were saturated with brake fluid, he washed them off and cleaned the drums before refitting the drums and sending the car out. During my observations I was also working and walking round the next work bay when I tripped over a box of tissues and damaged my nee on the floor.

Being rushed to the doctors advising him, the doctor examined my nee and said your alright it's only damaged tissues
