These days people generally, come on their own to the offices. They will have their own transportation arrangement. In some offices, they will be sharing their vehicles so that cost of transportation will come down. But some people try to use the vehicles of others and never bother about filling the fuel also. If somebody is doing it regularly we can say not to him. Once in a while or in case of any emergency, somebody asks for help we can consider. But as a routine somebody uses other's vehicle for their personal use, we need not consider their request and we can tell them that we are not ready to lend our vehicle for them.
