When I was in Japan, I noticed that a lot of the staff (especially in restraunts and train stations) did not completely say arigato gozaimas, it just sounded like they said "gozaimas" in a really long winded sound. Is this because they say thank you so many times in a day they just get a bit lazy, or is it that gozaimas as a stand alone term kind of just throws the kindness/respect your way?
Sorry for the romaji, work computers suck.
