I had something similar this morning from a very engaged and proactive in-flight lead (or whatever the title is). My first ex LHR Euro trip since 2019 and I wasn't particularly looking forward to what Heathrow had in store. Was a lovely touch to be recognised for loyalty, addressed by name and offered a bottle of water once boarding complete... and another toeards the end of the flight for my onward journey. It wasnt overly gushing or embarrassing, he got the tone just right. Great effort.
