I just told the woman at reception that I’d like to buy 24 hour access. She handed me a card with the rates printed on it and said that I can just buy it directly over Internet. (Right, like I’m about to give my credit card information over a public server!) Knowing it's also possible to pay with cash, I smiled sweetly, waved 10 Euros at her and said in my very best French:
Mais non, je préfére acheter vous! ( Which means approximately: No thanks, I’d rather buy you.)
Niiiiiiiiiiccccceee. I haven’t even been here 24 hours and I’m already puttin’ the moves on the staff!
