Friday nights - ugh
I have operated flights where large numbers of exceptionally merry/boisterous people have boarded, particularly on Friday nights, between NCL/LPL and BFS, and have made the decision not to offer a bar service of any kind. A firm but courteous announcement was all that was needed, and the Flight Crew and my Line Manager backed me up on each occasion. Rival Jet2, incidentally, does not currently offer any refreshments on very short sectors anyway. On each of my flights, several passengers not connected with the stag groups etc expressed their gratitude, and as the flights were all under 40 minutes long, it wasn't long to wait.
