Parvati didn't go to the loo. She went to the maitre'd stand, knowing that in a fine restaurant like this, they would bend over backwards for a patron.
"Excuse me, could you help me out? I'm in need of a room...as soon as possible. Could you tell me where I could get one for tonight?" The man at the desk smiled graciously and picked up the device next to him (muggles and phones, it never ceased to amuse her) and started speaking French. He looked at her, and turned a way a bit as he spoke more in the phone. Placing the device down, he smiled and said, "It is done Mademoiselle. I have found you an open room at George V, just down the road. You can check in any moment." Parvati thanked him, and asked. "Sir...would this hotel change British pounds? I'm afraid I didn't get euros before I left." The man smiled kindly at her, "But of course, they will take care of you there." Relieved, Parvati stepped towards the loo, only to see George make a bee-line for the door with their leftovers. Excellent, she thought.
"Well, it seems I've found us a room. Shall we go then?"
