Here is a comical video on eating sushi at a sushi bar. There is a lot of culture here, but, a lot of the things these comedians do are downright absurd so it might be hard for some of us to pick up on. Guess what is wrong in this video in the comments below!
Here's my favorite part:
In the case of business colleagues the lower ranking staff must pour for their superiors first. "Maa maa maa maa". You must say this when pouring a drin.k The person receiving the drink must say, "Oh toh toh toh." "Maa maa maa maa." "Oh toh toh toh." "Maa maa maa maa." "Oh toh toh toh." "Maa maa maa maa." "Oh toh toh toh."Maa maa (まぁまぁ) means something like "Now, now" or, in this situation, "Here you go, have a lot." Otto (おっと) means something like "Oops" or, in this situation, "That's far too much." So, while the one guy pours a lot and says, "Here, drink up," the other guy is saying, "Ok. Ok. Woah. Too much!" While it is Japanese tradition to pour for others and offer lots, you might see how this over-the-top repetition and insistence is not exactly customary at a sushi restaurant—or anywhere for that matter.
