Is that Usher at the next table? Please don’t gawk

Was that Usher eating at the Cheesecake Factory late Saturday night after his concert at the Sprint Center? It’s not unlikely — the California-based dining chain is one of the few restaurants on the Country Club Plaza that serves late on weekends.

A bartender at the restaurant told a Pitch reporter that the staff was sure it was Usher. For one thing, he was in town. “He looked just like him,” said the bartender, “but he was in a hoodie and sunglasses and it wasn’t like we could say, ‘Hey, are you Usher?’ “

Why couldn’t he? What is the proper etiquette when celebrities are in a restaurant? First rule: Don’t gawk.
