This is an interesting approach in Christian ministry, and there could be pitfalls and temptations and possible controversies but, hey that is what surrounds effective outreaches to those who really need someone anyway's. Wether or not the bartender has trouble directing someone to the Pastor isn't important, it is wether the bartender thinks they are qualified to council someone in need.
The bartender would be relieved of a duty they were never intended to have in the first place. Which would allow them to continue with their proper duties such as the rest of the customers for one, and more time to maintain their work station.
People who are spiritually lost and unfortunately don't know where to go, or who to trust, often find themselves confiding in people who haven't a clue as to what to say or where to direct them. Having Pastors in bars is the perfect solution for them not to mention, with the Pastors there it might make it much easier for the one who becomes too intoxicated to drive or make it home on their own, to get home safely.
If a bartender feels like an important aspect of their job is being taken away from them, well then maybe they should consider a career change. There is always the need for more Pastors, and I hope in the future even in bars.
