Question
What does one do if s/he is riding an intercity bus and expects it to get back in plenty of time before Shabbat, but there is unexpected traffic and the bus does not reach its destination until after the start of Shabbat? Does s/he ask the driver to let him/her off wherever the bus happens to be when candlelighting arrives, or keep on riding the bus to its destination? And if s/he has any possessions with him/her and the bus terminal has no eruv, what does s/he do about his/her possessions? If the bus terminal is far from home, where does s/he spend Shabbat? What about if loitering at the bus terminal is prohibited by law and there is no suitable place nearby?

May a Jewish person earn money via youtube.com or amazon.com? A Jew does not do business on Shabbat or on Yom Tov. Other people might use youtube or amazon on those days. Thank you very much.
