This is a small, family run place. They always look a little exhausted: for instance they hand-shell the garlic; one time I showed-up and half the table was covered with garlic clove peels.
That takes much more time and energy. They also serve the korean community; LOTS of korean people show up to eat here; nobody died yet.
“No one lives forever – the sad thing isn’t dying, it’s those that don’t live.”
I’m sure if you asked them to wipe the table, they would have. Remember to be polite and behave as a guest and you will be treated like one.
