I'm not sure about 'smoking manners' mean?
Hey, it's me again :D
I was watching a video and a man was asking some questions about the foreigners in their country. So he asked "What mistakes do you see foreigners make in Japan?" so a group of teens said something about it. Then the presenter said "What else? Their smoking manners?" and young boy became silent for a sec. then he said "Also, they use Suimasen too much"
So I think smoking manners means some kind of manner about smoking or sth. (Omg best explanation ever lol) But I'm confused with young boy's reply. I didn't understand why he said Suimasen thing. Did he just parried presenter's question, didn't he hear his question or do I really know what smoking manners mean? Sorry for that stupid-looking question. And if you want here is the video's link.
He asks the question at 5:43 https://www.youtube.com/watch?v=pEcDfLXz9Bo
Thanks already!

Answer

Suimasen  is actually Japanese. If you look at the top left of the video there is actually a definition of the word in the video. This is pretty common with Japanese videos, you need to be aware of these definitions popping up in available space on the screen.

The reason for this is that there are a lot of words in Japanese where we don't have a similar word or concept in English, so to try and keep the original meaning they will use the Japanese word and try to explain it.

English then adopts some of these, oniichan and sempai are 2 that come to mind.

Answer

It means "excuse me". The speakers are agreeing that foreigners use it too much in this situation.
