What Valentine's Day window display ideas work for non-retail businesses?

Valentine's window displays are not just for stores. Restaurants, salons, fitness studios, and service businesses can all use a themed window to pull people inside.

• Salon: a "Love Your Hair" theme with custom signage and a seasonal offer.
• Gym or studio: a "Fall in Love with Fitness" promotion with bold window graphics.
• Restaurant: a couples' menu or date-night special featured in the window.
• The display does not need to sell a physical product. It needs to communicate your Valentine's offer and draw foot traffic.
