RICHARD: Uh, what does [Sherry] do? Does she work?
CHRISTOPHER: Uh, she’s the East Coast sales rep for L’Oreal Cosmetics.
L’Oreal is a French beauty product company headquartered in Clichy, France, with a registered office in Paris. It is the largest cosmetics company in the world. It was founded in 1919 by chemist Eugène Schueller.
The US headquarters of L’Oreal are in New York City, but they certainly employ sales reps in Boston. Christopher says Sherry is the sales rep for the East Coast, as if they have only one! I’m pretty sure Sherry is only a sales rep for L’Oreal. Christopher loves to talk everything about himself up.
This does bring into question whether this business trip is really for Christopher, or was it for Sherry’s work? It seems like it’s actually her job that would involve travel, not his. Bearing in mind his comment about eating at White Castle (which is in New York), it could be that they were in New York for Sherry’s business, then decided to spend the weekend in Connecticut to see Rory. In which case, they could be staying as close as Woodbury, making their travel time to Stars Hollow even more achievable.
