It never bothered me but two years ago while returning to ny from Ca the plane was fine and all of a sudden it dropped. The flight attendants sat on the floor. Then one made his way to the speaker on his bottom and told us to remain calm and he would be around with napkins as soon as he got the OK. We also had received our drinks and were now wearing them on our heads.
Oh I just wanted to add that the flight attendant told us it was just like hitting a pot-hole in the sky. We have some pretty big pot-holes in NY but known as scarey as that one.
