Rob, yes I understand it is my fault if I took a "fleecing" from charter taxis. However, to my defense, I am not so good at bargaining for services. I am constantly worried about insulting someone over low-balling. You hear this all time time when it comes to home or car buying (if you offer too low of a price, you'll insult them and they won't deal with you). So when I ask the price and they tell me, I assume (wrongly?) that there is no wiggle room. It wasn't until after a couple of trips that I realized that bargaining is an acceptable practice. Although I maintain that the prices the charter taxis 'charge' (their first offer?) are still some of the highest I've paid anywhere. I would also classify it as a fleecing no matter where I was, whether NOLA, NYC, etc.
Also, I am not so gullible as to agree to anything or get into a cab without first coming to terms on price. That wasn't really my issue.
