I just made 30 euros drinking tea, eating cake and talking to a very interesting woman. I also met her husband who is the French translator of Harry Potter. Let's see if I can weasle some info about Book 6 out of him. But in honor of my first 30 euros made in France (I plan on turning it into a fortune, like in all of the American dream stories in the movies), here is a list of synonyms for money, thanks to Roget's II:

capital, finances, funds, cash, currency, lucre, wampum, bread, cabbage, dough, gelt, green, jack, lettuce, long green, mazuma, moola, scratch, brass, bucks, peanuts
