Hoosten..
I know for a fact that Virgin at that time were blocking the middle seat.
I was on the VIrgin flight SYD MEL on the day you mention (April 13) and I can assure you that the middle seats were not blocked off. Sure there were some that were vacant as it was not a totally full flight, but there were many rows, including mine, that had all three seats occupied
I understand your position on the pointlessness of social distancing in the lounge/aerobridge, when you are boarding an aircraft where social distancing can’t really apply, but really, a “a death stare” towards someone just doing his/her job and asking for social distancing on the bridge?
In fact the Cabin Crew, Check In staff etc should be praised, as on your flight (and every other no matter what brand) put themselves at risk due to having more close contact with passengers than you most likely would have had.
So as frustrating pointless requirements may be, perhaps cut a little slack, and leave the “death stare” for times it might have a place.
