Touts prey on newly-arrived passengers, taking full advantage of them in many ways:
They may not be familiar with the local currency
They may not be aware of the typical cost of goods and services
They are likely tired and jet-lagged and just want to get to their hotel
They may have not booked a hotel and are in need of a hotel
They are likely carrying large amounts of cash or wearing expensive jewelry
This is what you need to know about touts:
Touts are typical high-pressure sales people. They latch onto you and do not allow you to make informed decisions regarding your transportation options. They will make a healthy commission on where ever they take you. They will not be directing you to the airport shuttle, the hotel shuttle, or the public bus station. They will most likely direct you to a pirate taxi or an official taxi that is in on the scam.
We 100% guarantee that you will be ripped off, you may not get to your destination, you will arrive later to your destination than taking an official service, you will be told that your destination hotel is 'full' or 'a bad choice', or 'closed for renovations'. In some countries, following touts and entering pirate taxis could end up with you involved in a serious situation where you find yourself making a significant ATM withdrawal or worse.
Many airport authorities are aware of touting activities, but few enforce any rules and in some cases the airport was even designed to encourage touting! Some counties are very corrupt, so try to do a little research before your trip.
Discussing a price with a tout indicates your interest and make them even more hungry. So unless you are serious, never ask the price. This rule also applies to dealing with vendors on your travels.
Not all touts are bad, although most are. In smaller airports situations may arise where official taxi drivers or shuttle drivers themselves solicit passengers. This can get you a seat faster and on your way. It could be a question asked of you, such as "You need a taxi sir?" If your response is "no", and if you are not hassled any further then likely this is not a touting scam -- but use your instincts.
