It is impossible for visitors to know all places where PC are located but by asking, you sure will find your way.
If the weather is cold avoid drinking too much beer if you must go on a long journey.
If you are a traveler do not forget to check places where there are free toilets closer to the place you are visiting you never can tell. The embarrassment of doing it on your body is worst than asking for a place where you could do it and say thank you!
