Some people love coffee and some people really LOVE coffee, and obviously their favorite mug. This motorcyclist must be in the latter camp because he recognized what the loss of a dear coffee mug could do to a person.
The biker, who was filming his commute with a helmet cam, saw that a woman had left her coffee mug sitting on the back bumper of her SUV.
The biker bravely pulled up beside the woman, in moving traffic and grabbed the mug. For those of you unaware, the throttle is on the right hand side, making this a tricky maneuver. We can see the moment here:
He then passes the mug back to the driver, while still moving:
Well done good deed biker.
