The tour guide had a lot of knowledge of the mines. However, we were not impressed with a number of things on the tour. The guide left us standing while he went to get some hot soup, which we had to smell in the van during the tour. He ate it in front of us and did not talk at points because of it. He made no effort to open the van door and assist us in or out of the van. He insulted the people who live in a nearby town, insinuated they are all stupid, after he had been told some of our tour group lived there. Not good for business. Too bad, we were really looking forward to it and were disappointed.
