Matilda walks into the bar, carrying a bag of books that's considerably larger than she is. She's looking at it all the time she walks towards Bar, which is a good hint to those who know her that she's surreptitiously levitating it.
When she reaches Bar and sets down her bag, she
sees
the sign about tabs and immediately has a look at the tab board. She gives it a frown, blinks twice (the amount of time it takes her to calculate what percentage of a week's pocket-money it's going to take to get rid of that) and makes a mental note to lay off the fried pancakes. Then she turns back to...
...the door back to her house, which isn't there.
She looks up and sighs. "That really isn't funny, you know," she remarks to the general vicinity. "At least I have all the books I was going to give back to wherever I borrowed them from..."
Then she takes out her notebook from the bag and scribbles
a note:
Mr. Giles,
I've finished with this book, so I asked Bar to give it back to you for me. It was certainly a very interesting read. Hopefully I shall see you again soon and you can recommend something else to me, either on the same subject or a different one.
-Matilda
She places it and a very large book of demonology on Bar and asks politely if they could please be delivered to Rupert Giles, following which she
requests a room key. On the little tag where there should be a room number, the key says simply '
Turn Left'.
[Hopefully it's okay to give my character a wonky room key that gives directions instead of having a number on it. I just thought it would make things more interesting.]
Some time later, Matilda emerges from the residential areas (sans giant bag of books but carrying her notebook and pencil) and takes a seat at Bar, frowning pensively and not eating anything, not even fried pancakes. Come ask her what's wrong, O sensitive patrons!
