Our reading
An editorial interpretation.
A polite but firm correction: the speaker addresses a man respectfully as Sir, then points out that the equipment is meant for children and that sleeping on it is not allowed. The earnest, rule-minded civility contrasts with the oddness of having to state something so obvious.
