There was an older brother that owned some type of delivery company along with his, I believe, non-jw brother. Their kids worked for them, and a number of men from the local congregations. I guess the jw men & their wives all assumed they would get assembly/convention days off w/o asking. I was speaking to one of the wives and she was pretty upset that her hubby had to work on an assembly day, as bro x KNEW they had the assembly and didn't just schedule the brothers off! Never thinking ahead to the fact that 1. he probably wasn't the one doing the scheduling and 2. others had probably REQUESTED that day off! There must have been a lot of bone heads complaining about it because there was a small comment made from the podium at that assembly that if you worked for a witness, you needed to be responsible for requesting theses days off, not just assume you were getting them.
There was the elders son who was a nice enough guy, but when he did some remodeling work for a single sister(she had some money as she made good money), he goofed up. He made a bar the wrong dimensions, and when she called him on it, he told her if she wanted it corrected, she would have to pay for it, that he wasn't going to eat it! She had family in, so she wasn't all alone, but did this fool think anyone else was going to hire him? His work was nice, but it was still not they had contracted for! She just accepted the wrong work to avoid confrontation.
I know of other stories of foolish jw workers, but I also know of some who give their best to their employers when they are at their jobs. Probably reflects the general population, but that is not what they say from the podium!
