Not to belabor the point, but photo of the reception is below. In my case, there was a single receptionist at the center and we were all queued behind her, and behind us was the main entrance. A second staff member came on duty to the right (where you can see staff members in the photo) and called the next person in our line over. The person behind me then went over there and stood behind the person who had been called over (same place as the 2 customers in the photo). Everyone else in front of me and the 4-5 other people behind me in the queue stayed put.

I guess this could have just been confusion but I have seen behaviour like this called out before in the UK. Anyway, again a very minor thing, just curious whether anyone would do what I did. Equally, do people think he could have had a valid argument against me for going ahead of him?

And to be fair to the staff involved, they did basically call me over instead of the guy standing at their desk, although they looked confused.
