BS. I've long since given up being the gracious tourist to some lying time share hawk who won't take no for an answer. No Gracias and a smile to a Mexican time share hawk doesn't mean no to them.
99% of the time they aren't even listening to you reply to them. Pay attention next time and say "Bumble bee" or "Potato" to them, they aren't listening to your response, they keep going "Hey Amigo, where you staying... where you staying.... blah blah blah".
They aren't listening to your response, you're fooling yourself if you think you're having a conversation with a time share hawk. They see you coming they start unloading the speal as you approach, as you get close to them they are still babbling and as you walk on by they are still talking to your back. You're nothing but a number to them. I've long since moved on for feeling sorry for ole Pedro and thinking he is just trying to make a living. This isn't a war veteran missing his legs, it's a time share hawk targeting a gringo to separate him from his money and time.
What are you guys doing, shaking hands and patting all 10 of them on the back, giving out hugs to them all at the airport? No gracias amigo, hey... looking good.... nice one... almost had me... hey, good one, you too, yep, 8th time was almost the charm! No gracias...
screw that, just walk on by them and let them babble on, they will quickly forget you in half a second as the next gringo victim appears.
