There's haggling where you actually enjoy the process (i.e. Turkey, visiting the bazaars, you get to haggle, then you get invited for some cay w/ the vendor, talk a bit, that's really enjoyable) and then there's outright scamming. Friend of mine went to Egypt, really wanted to ride a camel. Agreed on a price, rode the camel, and at the end they wouldn't bring the wooden thingy so that he could dismount, and they were asking for more money. That's not enjoyable at all.
