One common way: you go for a camel ride. The camelier offers a very cheap price. He takes you far out somewhere. You get off for a bit. If you want to get back on to go back, he will overcharge you. Otherwise you walk back and that is worse.
i guess you might be ok if you are cocooned in a safe travel group. I travel more independently, freely and let things come to me. Going on planned group iternary isnt much of an interest for me at the moment.
I absolutely hate tours and being penned in. However, if I see expats or locals in a tour group, it tells me there's some value there I'm missing. Served me well in India and parts of South America, for example.
