A thief stole a woman’s iPhone off a counter at a Bergen Street restaurant on Feb. 24 — then derided her when she called to demand its return.

The 31-year-old customer at the excellent Sun in Bloom restaurant between Fifth and Flatbush avenues told cops that she left the phone on the counter at around 12:30 pm. Later, when she dialed her own number, a man answered and said, “Dumb b—h, now you’ve learned your lesson.”

Ouch.
