Getting Screwed over in Morocco

This weekend I went to Casablanca and learned some important lessons:
1) Always have the meter running in a cab; they will always overcharge you otherwise... we had to pay 100 dinars to leave a club at night while our friends paid 50... we thought that that was the night price. On the same note... the taxis waiting at a tourist spot is much more likely to try to screw you over... we learned that sometimes you just have to get out of the taxi.
2) NEVER get round trip tickets for the train; they only work on the day of your ticket and the conductor AND supervisor will not care. It seems that in Morocco, the customer is always wrong. We even had a nice Moroccan try to help us but it did not work. Me and my friend had to pay an extra 37 dinars (only 4.50 in dollars, but still)
3) Don't go with people who take you to a place they know... they're always going to take you to the most expensive place and where they have friends. People in Morocco are nice, but if they see you as a tourist, they're going to try to make you spend money.
All in all, even getting screwed over for the taxi and train (of course they both happened to me...) I probably spent 65 dollars for a night at a hotel, a fancy dinner, train to and from Casablanca, a club and a few drinks, breakfast, and ice cream. That at least makes me feel a little better.
