I like to book them early afternoon or early evening. You will have more energy and higher levels of testosterone earlier in the day than late at night.
And if you really enjoy them, you may be able to extend time with them if you start earlier.
Also, it might not be an issue with the independents since they are probably low volume (ie one client per day or less). But at a place like [Redacted], they might see multiple guys during their work shift. Wouldn’t you want to be her first customer of the day rather than the last?
