Tabatinga is probably the worst town in the world. Everyone there is a thief, liar, con artist, prostitute or drug dealer. Most people are all of these things rolled into one.
Never allow anyone to touch your luggage because they all have drug residue on their hands. Never allow the hotel to call a cab for you because the rate will be double. Plus, the cab will probably have drug residue in it.
In short, the town is worthless!
