Question about Carrie signing autographs

i've seen some videos on youtube of carrie signing autographs before her concerts. does she always do that? i was just wondering because i am going to see one of her FL shows and i thought it'd be so cool if she did that. or is it one of those things where you wait all day for her to arrive? just wondering. i will really appreciate it if someone can help.
