It was there but never consumed and indeed quite rare for the cockpit to receive a standard pax tray, on most flights first class catering was offered, no plastic trays or plonk. No one felt the need to virtue signal by having it taken away, why would you ? why were you so concerned about what others may think ? you didn’t drink it so that was that
I suppose people were were less interested in what others may do or say and were overall far less judgemental, everyone was pretty grown up about such things .. pre social media days .
