I can relate to your discomfort. I have to say this is one of the reasons why I'm not going back to a group at the moment, as I'm not massively keen on any old soul seeing how much I've put back on!
I agree that they shouldn't make a comment such as this but the weigh in person is not "any old soul"
As already said, the weigh in person will usually be a very long standing and trusted member of the group, they have to abide by SW's confidentiality rules and will NOT discuss weight. They are also usually the person the members ask questions of when the C is not available (as Avisk said)
I weigh in my group - someone said their WI lady was not the quietest person, well nor am I but I would never disclose anyone's weight and as someone else said, it's all numbers! The people go through that fast it's card in, write down, close book, move on. That's it. It means nothing to us - just numbers.
The weigh in time is not time to have 5 mins with your consultant, I have them queueing out of the door - there's no way there'd be a minute to chat at the scales.
I get a bit disgruntled when these threads pop up but I can see why people are surprised the consultant doesn't do the weighing so I guess they are good threads.
The consultant does the new member talk while I weigh and if there are no new members then she will either chat with anyone who wants her help or help with the weighing - we usually have new members though!!
Please be assured, the weigh in person will not discuss your weight - I don't actually care what the figures say for people as long as they are going in the right direction.
Put it this way - if YOU were the weigh in person would you discuss people's weight? I doubt it very much, so why question the integrity of those who do weigh?
