I've never, ever had an FA in F (or any other cabin) turn down my request for another drink.
You must have been, or appeared to be, visibly inebriated.
appeared
was a 10 am fri morning flight (my rav said it was ok)
i did two things that can make them assume i was gone.
1. needed the bathroom very often due to drinking and was a) very embarrassed to keep going b) scared the other passenger with me was going to need the bathroom and i couldn't lock it for two hours on flight while it was shabbos. so to avoid being seen going to bathroom very often i climbed over the middle section of first to get to bathroom so as to avoid kitchen area, they must have seen me!
2. shabbos crept up on me and i forgot to turn on my lights so for the time that it was shabbos i couldnt sleep without a drink and was very bored. i wanted to use the lights of the tv to read/learn. so i laid down backwards on my seat with head by tv on foot rest (or whatever the real name for it is, ottoman maybe?), tuchus in the air and feet on my seat. i know they saw me doing this!
hope you all have a good laugh at my expense.
other wise was an amazing flight
