But almost all cities have some type of bus transport system, each offering a variety of services and features. It may be a public transit system operated by the government or a local organization, a collection of privately owned and operated buses, or a combination of the two. Observe the locals to see how they use the local buses. In some cities, you can enter from the front or the back door. Sometimes you just hang off the side.
Payments methods vary as well.
You may never have to show your ticket to an official. On some buses, you will have to throw your bag up on the roof or stash it underneath. Try to get a seat, or stand, where you can keep your bag in sight. Buses in any country can be very stuffy when packed with lots of people. Some buses may even suffer from sudden mechanical problems, leaving passengers stranded.
