Brazil vs Japan Culture Shock

 Saw this video today and it almost moved me to tears because as a person who grew up adapting to vastly different cultures, I could see from both sides in this video.  In the vid, a Japanese waiter endlessly apologizes for his server spilling some shoyu sauce on a Brazilian tourist.  At first it is funny, but then it gets more and more uncomfortable as the waiter keeps apologizing and the Brazilians keep trying to cheer him up.  I can see from his side because I know from living in Japan how dedicated to service the culture is, and how serious an apology is in a place of business.  I also feel for the Brazilians because the apology doesn't hold the same importance, and all they want to do is cheer him up.  They do their best, but, probably because they are louder than the waiter is used to in his culture, and everyone is speaking a different language, he ends up in tears. An unfortunate cultural misunderstanding 
This is a great reminder of how different cultures can really be, and how helpful it is to know about the cultures of both your hosts and your guests.  What would you do if you were in either side of this situation?
