Mine typically replies to emails the next morning, sometimes sooner. Though I emailed him yesterday afternoon and haven't heard back yet, so I'm concerned he's annoyed with me. Yes, I know it's Saturday, but he typically replies on the weekends and even when he's out of town. He charges if it's a particularly long reply, though that's not too often. But his policy is, he always responds in some way. Which I appreciate.

He only allows texts for scheduling, and he usually responds within a few hours for those.
