Las Vegas is not that great for walking. There is some form of public transportation, but it is pretty well hidden. When you are in a rush from one show to the next, the standard option is taxis. But since everyone else is also trying to get a taxi, the line can be very long...
Speaking of taxis, in the U.S. it is mandatory to tip in all kinds of situations. Taxis expect 15% tip or more. We tipped one of our taxi drivers almost exactly 15% percent but he became angry and said that it was too little and that we needed to pay more. Despite not having been a particularly great driver, and despite having spent some time (with the meter running) trying to catch up to a guy who cut him off to yell at that driver (the other guy was driving like a crazy person so yelling at him was not strange, but perhaps he could let it go and just drive us to our destination if he is getting paid by us).
In Japan and in Sweden, people get a salary that is enough for them to live on so there is no tipping. Some people tell me that if there is no incentive of a tip, service will suffer, but I must say that Japan has much much better service at restaurants, taxis, hotels, etc. than anything I have experienced in any country with tipping. Much much better than in the U.S.
