Good idea but that’ll reduce the workload and maybe the number of people employed! Plus, the taxi/tuk tuk drivers lose their share to get to Prom and Prom loses the coffee customers then Promenada closes and all the workers there lose their jobs and can’t buy food from the markets...and all because stamping at the airport is a good idea! 😁
Just buy your friend a cheap bus ticket to another country. Send the ticket to her and she’ll be covered should the airline ask. Ticket can then be used, sold or thrown out.
