Why it worked
The video likely worked because of its relatable humor and the creator's willingness to engage in a slightly awkward but funny social experiment. The "rejection therapy" premise, combined with the cultural nuance of name pronunciation and the common experience of ordering coffee, created a unique and shareable scenario.
Summary
A person attempts to get free coffee at Starbucks by using a "rejection therapy" tactic, asking for their name to be spelled "Josh" instead of their actual name, Rohan. The barista initially struggles with the pronunciation and the concept, but eventually complies, leading to a humorous exchange about the process.
