Our reading
An editorial interpretation.
The speaker is overflowing with delight at their own good fortune, declaring themselves the luckiest person alive. The moment a customer knocks, though, the happy mood is briskly overruled by a flat refusal: the place is closed. The joy is real, and it clearly outranks business.
