Saw the same notice in Neukölln, Berlin, once, about 15 years ago.
This is the sales outlet of Jenny Bakery (yeah, no apostrophe-s) at Mirador Mansions, Hong Kong. Indeed, I had to line up together with a large number of PRC Chinese, all stuffing their trolleys with a dozen cookie boxes each. I bought one.
Those Prussians surely love their Thai… food. I gave up taking photos after having visited about 20% of the “food stalls”.
