Writing on Starbucks in Paris, Emilie Boyer King quotes the boss of a neighboring café, who says philosophically.

I say, the sun rises, and there's a ray of sun for everyone.

It sounds like a proverb, and I found this from the French writer Jules Renard, (1864-1910):

Il y a de la place au soleil pour tout le monde, surtout quand tout le monde veut rester à l'ombre.

"There's room in the sun for everyone, especially when everyone wants to stay in the shade." There's a kind of sweetness to see the cynic's message being turned upside down into something more optimistic.

That said, on the few times I've had Starbucks coffee it was a real disappointment.
