Celebrity divas take note: U2 superstar Bono was spotted patiently waiting for 90 minutes for a table at a restaurant in New York City.

The New York Post’s Page Six reports that the Irish rock star was in good spirits, ordering cocktails and pizza for his nine pals, while they all waited for an hour and a half for a table at Bocca di Bacco.

Bono and his entourage showed up at the restaurant on Sunday night without a reservation. Despite his A-list status, the U2 front man had no qualms waiting that long for his party’s two tables, and even left a hefty tip for his server.

An onlooker told the Post: "People of Bono's stature could take a few lessons from him on how to behave in public. He never complained about waiting, paid the $1,500 bill and left a generous tip."
