It's rude to leave a champagne glass half full

For some reason I thought gate closed at 2155, not 2135. Left the lounge at 2128, went the wrong way to start with (!!!), got stuck on a travelator behind some people that wouldn't budge, sprinted to the gate to get there at 2138 with >100 people still left to board.

In the end the plane was late because they had to offload a bag, and they'd lost it (not in the bin they thought it was).
