I read a sentence in Word by Word by Kory Stamper which was:
Traditionally, the editors ring the cafeteria in groups of twos and threes, clutching our wine and murmuring quietly among ourselves while the marketing and customer service folks whoop it up in the centre of the room near the shrimp cocktail, having quantifiable, voluble amounts of loud fun.
First, cocktail is a drink not a place, so why does the author say "near" the cocktail. I think it would have made more sense of she had used cocktail bar. Second what does "shrimp" mean here?
