I absolutely rubberstamp at least one of Lea's drunk bad karaoke making it to Youtube, unless Aqua is just too good of a soul to put it there. (Then again, someone else could have, lol).

How long has she been tending bar? If it's less than six months, Lea wouldn't know her; otoh if it's longer than a year, they might talk enough for her to consider her a casual friend rather than an acquaintance.
