That's true. Look at Kuja in FFIX. He's a bad-ass in his underwear.

But back on the topic, it all seems "common sense" to me that you meet them in a place that fits their personality. It wouldn't make sense to meet Aeris knocking the stuffing out of guys at the beginning of the game, just like it wouldn't make sense for Tifa to be tending to the flower garden. It shows that Square put some thought into the characters to make sure that they are true to their personalities, which is a flaw that a lot of games tend to make these days, where the characters' personalities are sacrificed and twisted just to make the story make sense(which it still doesn't a lot of the time).
