求助：关于华沙机场至中央火车站的公交车
要搭乘175路在DWORZEC CENTRALNY下车，之后搭火车去Lublin.
请问怎样买票？
得到的manual如下
Change your money - you will need about 150-200 PLN.
Go to the newsagent’s shop or automatic machine to buy a bus ticket for 2,40 PLN. (beelet normalnee – in Polish). Although you might be a student, there are no discounts for foreigners on buses, trams, metro or train. You have to study in Poland to have discounts or have a valid ISIC card which gives you a 48% discount (so the ticket will cost 1,25).
但是我想公交车不至于125兹罗提单程吧。。。
晚上抵达，在莫斯科到华沙的航班上遇见中文超好的越南人，告诉我不安全的，于是我选择taxi. 在华沙机场一个警察帮我叫了出租车，至中央火车站，75兹罗提。
