Should this person's work compensate him for a stolen bike?

My gentleman friend works as a bike delivery person for a restaurant. He often brings his own bike to work as he prefers riding it to the work bikes, and he has no problem letting the other delivery guys use his bike.

Last week, one of the other delivery guys was making a delivery with his bike and the bike was stolen.

The bike is his primary form of transportation, including to and from work. Not having a bike is a serious inconvenience.

Should he be compensated for the stolen bike? If so, by whom and how? What would be a fair way to ask for compensation?

I am especially interested to hear from small business owners. (I personally think the owner of the store, having enjoyed the privilege of using the bike, should offer to replace it.)
