Thanks for your feedback on this.
I'm in Western Europe (not the UK nor Ireland) and here first it was a work reserved for pioneers but then more brothers were needed as pioneers realised it is a stupid job where no success at all and some turns were uncovered. In my congo there's also the problem of the few brothers that can speak fluently the language to be assigned and that we're a small congregation.
I have decided to start doing it once a month and in a couple of months saying I won't participate in the arrangement for personal reasons. If they insist, I can say I'm working full time during the week and I need time to go shopping and other things.
By the way, in my country there are congos allowing appointed men with bears and others that don't accept it. It all depends on the desires of the BoE.
