LHR to DXB: everyone is waiting at gate, tons of gate lice as always, priority boarding has started for special assistance / families with small kids / group 0. Middle aged lady decked-out in Gucci arrives to the barrier - no hello or greeting, just casually states "Group 1" to the gate agent. Gate agent replies "please take a seat, we've not started boarding group 1 yet". Lady is taken aback "well who are all these people already going through?". Gate agent: "these are passengers who need some extra time to board". Lady: "I need special time to board as my ankle is swollen up and I'm group 1 anyway". Agent sighs but lets her through.

Funny how I saw her literally speed-walking to the gate perfectly fine.
