How do I handle the goodbye at the end of a Dubai escort booking?

Walk her to the door, thank her for the evening, and give a genuine compliment. A brief hug or kiss on the cheek is appropriate. Do not linger or make it dramatic. She does this regularly and prefers a warm, confident goodbye over an awkward extended farewell. If you want to see her again, say so: I would love to book you again next time I am in Dubai. Simple, warm, done.
