What they offer is nothing more than cheap imitations at outrageous prices. I myself was accosted on several occasions. Interestingly, once I spoke and the vendors realised I was an Egyptian, their whole attitude changed. It is my sincere hope I shamed some of them. The result of all this unseemly chaos is that nobody buys anything.
Tourists are smart and generally savvy.
Only a very few of them fall into the traps laid out for them. It saddened me to see the way the vendors and many of the local service providers act. From cabbies to the horse-carriage drivers to the felucca operators, everyone is trying to take the tourist for a ride. I was dismayed to learn that some sites are no longer visited because of the way the tourists are treated. The temple in Esna is a sad case in point.
