Seen it posted here before but never experienced it until today. Captain gave all of the F passengers his business card with a personalized note. And the card had his Twitter handle. He also used the FA intercom in the cabin to tell us about a ground stop delay, which turned out to only be an hour but he let people get off in the terminal. I didn't because I scored a rare upgrade as a Gold and wanted to enjoy my PDB. It was an awesome crew and flight and I didn't even think about the minor delay.
