It very well have been that she was joking. If I saw a cop and did that and smile the cop would probably smile, too.
In Austin when Bush won there were a bunch of state troopers standing around and asked “Which one of you goes and finds the women for the governor? Oh, wait. Wrong governor.” They all laughed.
I once had a boss who told me joking is something you do on your own time, not on my time.
I really doubt it.
