A young lady takes the table.
She looks like a student, perhaps from Japan )her cap has the Rising Sun on it.)
She picks up the plastic cups and throws them into a dustbin.
She then goes over to the counter, takes some tissues and starts cleaning the table.
Some of the staff notice
And run over to her and say that she should not bother. They will clean the table.
She answers:
"No, it is all right. It is my table, no?"
A massive lesson there.
