In any case, do not negotiate with the conductor if you do not have a ticket. They can offer, as well as the police. But they will only drag you from one car to another, not only demand a large sum, but also threaten you that you will end up on the street. As annoying as possible; I agreed on one place and realized that I was being dragged from one place to another, I landed without paying anything and went to Tashkent by taxi for 200 thousand sums, they demanded 300 thousand zoom from me. It is better to buy a ticket for much cheaper in advance, if you do not have time, then I suggest you go with a taxi.
