Planning on teaching in Korea (of course English) and hoping to travel all over the country. What I am concerned about is the long trips (3 hours or over) that you have to take on bus rides. Do these buses have bathrooms? I heard that during these trips people like to eat and specifically drink? During a bus ride and let's say for lack of a better word have to pee or even worse go #2, what do people do during these types of situations?I'm a big fan of bathroom-related questions. You can tell a lot about people, cultures and history based on their bathroom habits, jokes and facilities.
I personally stay away from a lot of bus travel for this very reason. First of all, no buses available to the general public have bathrooms on them. Instead, the driver will pull into a very busy rest-stop at the halfway point on most trips over 2.5 or 3 hours. Of course, not everyone has the exact same bladder functions and this presents a problem.
In all honesty, you have one option: begging the driver to pull over.
In most cases, they will. It's not totally uncommon to see a bus in the shoulder and a lone passenger ducking behind the bushes. It's embarrassing for sure, but much better than, say, pooping in your pants.
Koreans have largely gotten used to this arrangement and since they're also the world's greatest transit sleepers, they generally doze through the entire process.
In other words, make sure that you're empty before the trip and don't booze too heavily the night before.
