Every escort is weighing up the time he'll spend for the entire event, including transit time, against the money they'll get. If you live in an area that is remote from the area where most of your local escorts live, there's an opportunity to sweeten the deal a lot with transportation thrown in. Because Uber cost way less than 300 an hour. Think about it, if you can save your escort an hour of time for $60, that's beneficial to both of you.
I'd never ask a client who lived in Midtown for an Uber. But if you're talking Nassau County or Newark, for sure I am.
