while there are some perks to being CO (not the least of which are the "green handshakes"), it is a difficult lifestyle.
It can be.
But there are many districts where wealthy dubs reside and many times they take care of the CO's in style. One CO I got to know well told me about a circuit in a western state where two congregations competed (not his exact words) to out-do each other in generosity towards the CO. Sisters took his wife shopping at every visit and burned up their credit cards for new clothes. He was taken to a men's store to buy new suits, golfing on Monday (CO's "day off") or skiiing in winter. And the green handshakes (actually the money-filled thank-you cards) sent them on the road with a pocket full of cash.
This was offset,by those rural congo's where the generosity was a little more limited - but even in less affluent congos, the sheep were sometimes surprisingly generous with money. It only took one well-off family to "adopt" the CO to fund their living expenses. There were a few congo's that were the exception, but on balance they lived quite well.
Later, they were transfered to another circuit where the congos were less well off and they had weeks when they were broke.
So it all depends on where "mother" sends you.
