TBH I am not sure the GB run around looking for photo ops. From what I witnessed at Twickenham 3 or 4 years ago at the international convention was the almost hysterical reaction of the R&F when seeing one of the GB (in this case Sam Herd). It's them that want the photos. In a time where it is possible for any of us to have an online video presence it's not surprising we see so much more of them and it's human nature to react like this when in close proximity to someone considered to be important.
I am sure the egos of the GB are nicely boosted and they are certainly no shrinking violets but it's all just a reflection of society and contemporary culture as a whole.
What's disappointing is that no one seems keen to ask any questions of the GB. I'd love to ask them any one of a number of pointed questions. Then take a selfie whilst they run away.
