I hate to say it, but back in the day, there was actually an unwritten "pioneer" rule to take only other pioneers with you on your "easy time" - bible studies, return visits, standardized business (laundromat) terriroty, etc. That way you would be helping your fellow professionals share time - not wasting it on mere publishers.
Every so often, the CO would chew us out about taking the publishers with us out in service instead of going off by ourselves. Idiot - did he think we were just going to give up our secrets on how to lurk out our time so easily???
