How would would you say "where is the toilet?" more succinctly with the context up front in English? If someone came up to me in English and said "toilet where?" I'd presume they're either rude or English isn't their first language.

There are formal and informal ways to say thing in Korean, for every day stuff it's often just a matter of changing the suffix, for some stuff it's a different word, for example 감사합니다 Kamsahamnida is thank you to anyone, but 고마워 gomawo (thanks) only to a friend.
