How to trick a tourist

We have been in Morocco for a week now and are slowly becoming wise to all the tricks that can befall a tourist. That said, I got tricked again this morning; I am so gullible. The most common trick is a guy will come up to you as you are poring over the guidebook trying to work out where to go and he'll ask you what you are looking for. You tell him you're looking for a supermarket and he'll say "it's that way, not very far." You'll set off in the direction he pointed and then all of a sudden he'll appear again and say "no, you're going the wrong way, it's this way, follow me" and its at that point that you have fallen for the trick and will have to part with some cash at some point, even if its just to get rid of him.

We have fallen for this trick or a variation of it at least 5 times.
