In that case Sago I would agree that, to me, she is rude. I wouldn't be offering her accommodation again.
However, I often think things people do are rude beyond belief when they think is is the norm. People shouting on phones in cafes, people interrupting conversations to take phone calls (except in urgent situations), people who use my drive to park on when visiting their friends, people who allow their children to jump all over seats, people who can't say 'excuse me' and just push you out of the way... the list is endless.
