Who runs a retro?

Excuse me, could you elaborate on the term "retro" in the context of your question? Are you referring to someone who operates or manages a business or venture that specializes in vintage, classic, or old-fashioned products, services, or experiences? Or perhaps you're asking about an individual who oversees the organization of a retro-themed event or activity? If my assumptions are incorrect, please clarify further. I'm curious to understand what exactly you mean by "who runs a retro," as the term itself can have multiple interpretations depending on the context. Thank you for your time and consideration.
