I was wondering about having to go in the service - the brothers used to say its all about being seen. In other words as long as your at the meeting for field service you can then go and do what you like. Ok not always, but there are usually those who want an easy life and are happy to cruise around in the car or stop for coffee etc. Also I think it would be interesting to bring out some of the real meaning of the scriptures - again would need a like minded person to work with. Then there was a Min servent that would announce he was going on calls and was meeting someone, or couldn't take someone for one reason or another, and basically stayed out for a while and went home when he deemed it a long enough time. So maybe you can see the ministry as a challenge to get out of without being found out
