Thanks!
I'm no longer the OP now that my post was moved into this thread but I just wanted to thank everyone who responded to my question about converting dollars to rand back to dollars. I tried Mia's approach of offering a middle ground, but was immediately shut down as I expected I would be. "Don't let the door hit you.." was pretty much the response. I ended up cancelling the tour over this issue. It was a learning experience. I've probably done close to 50 tours at least (day tours, multi-day tours, and so forth) that I negotiated from home in various currencies or in dollars, and was always mindful of the currency issue - maybe I was lucky until now, but everyone seemed to use the same rate or close to the same rate no matter where in the world we would be travelling, until now. It was really sad, but I did feel as Doc Savage pointed out - if this was their attitude now, what might result while we were travelling. Percysmith, your links to Paypal did provide insight as well. Never again will I deal in dollars when getting tour quotes - they will always be in local currency and understood up front that they will be charged in local currency. Thanks again for the help.
