I'd like half hours if I could get them one after the other, just bang, bang, bang. You know, one at 12, 1, 2, 3, and 4. With a half hour in between to rest, eat, shower. That would be more lucrative and easier on me mentally. But hour clients are easier to schedule in a way. Or, rather, if I'm only going to see three clients it would be better if they were all one hour or more.
I run out of charm with even the most lovely men after two hours.
