Vacation activities come with expectations of professionalism, especially when paying premium rates for guided experiences. Snorkeling instructors hold positions of authority during lessons; they control safety equipment, determine group movements, and often provide one-on-one assistance with mask fitting or buoyancy techniques. That professional dynamic creates inherent power imbalances where friendly banter can quickly cross into inappropriate territory. When instructors use their role to make romantic advances toward clients, they're exploiting the trust customers place in their expertise. The behavior transforms what should be a relaxing tropical experience into an uncomfortable situation that leaves couples questioning whether to speak up or let it slide.
