I don't know. You know how stereotypically, when you think of Greek, you hear 'os' at the end of everything (think Theodorakopoulos)? When you hear Korean, eumnida and eyo's seem to always come up. Maybe -eumnida isn't really that common, maybe it's just cos it's in the only word I actually learnt. xD 고맙습니다
squance: i looked at that guide, and a lot of clubs are offering showbags. the thing is, most of them will only give you one after you've joined them.

editz: google is my friend
There is also a "polite formal" style, which you will find in some of the phrases above; in this style, declarative sentences end with the particle –습니다 / -읍니다 "-(s)eumnida" and questions in –습니까/-읍니까 "-(s)eumnigga."
