I've heard that fancy lodge in Purros taking a lot of stick. When we arrived at Purros we'd almost run out of cash (yeah.... cough...) and had a DRZ with a broken radiator, so we asked around for help there. It was around 5pm, and the guests were out on a game drive, but the staff were actually quite welcoming bearing in mind the filthy, low rent state of our appearance. We sat around the pool and had a beer, and then they set us up with one of their 4x4s to guide us to the petrol depot in the 'city' centre (haha).
To be fair - they are high end, and if people are paying $800 per night or something for a small, exclusive experience, it probably isn't reasonable to have some dirty bikers hanging out at the pool and abusing the place when they don't intend to actually stay. They were actually pretty helpful. Even gave us an egg for Tom's radiator, that the chicken shit was too scared to throw in.
On the other hand, the guide from the Wilderness Safari's Lodge we (or just Tom did) bumped into on the Crowther was downright rude. And that's after some of their other guides had been extremely friendly and taken us to see some elephant from the river banks. I think it's just luck of the draw...
