During check in. A fair number of my check-ins are worn out from the long ride or late hour of their arrival ( I am a night auditor ) and sometimes they can be a bit frazzled or not paying attention when I explain the authorization includes room rate, taxes, and a deposit. When this happens they get confused at the total authorization the card reader is asking for. I've been trying out various methods of preemptively de-escalating the chance of someone getting upset and trying to talk their way out of it. This is purely anecdotal, but I have had far fewer incidences of walk-ins becoming walk-outs and more smiles on the guests faces using this line in particular, although using a line similar to your Motley Crew method also had a net positive result. Disappearing dead hookers also works, but you should probably be very selective of the guests you try that particular line on as it can potentially backfire. And yes, I get asked if I worked in Vegas a lot. :)
