C.

While A,B, and D have probably happened more than once, the answer according to Food & Wine magazine is C. Guests (known as “campers”) who overstay their welcome are one of the banes of a restaurant’s existence. Especially guests who, an hour after closing, are still sipping the one inch left of their lukewarm Chardonnay. According to the magazine, here are four other signs that it’s time to settle up and head home:   You smell the scent of candles being blown out, there are trash bags being drug out the front door, the bartender isn’t as friendly anymore, and the table has been completely cleared.
