[Batman] When does Alfred manage to get some rest?

Alfred is probably the most loyal and committed member of the Bat Family: every night when Batman is on duty he provides him with invaluable remote assistance from the Batcave and also helps him before and after the patrol. 

The problem is that Alfred has also a very demanding job as a butler of one of the richest men in the world, looking after a giant mansion and several complicated tasks that would be extremely demanding even if that was his full time job.

Bruce manages to get some sleep during the day justifying it with the fame of his public persona of an hedonistic billionaire, but Alfred doesn’t seem to be sleeping during the day, on the contrary he uses to greet his master when he wakes up or he prepares personally his breakfast/lunch.

That being said when does Alfred manage to rest or just sleep for enough time to not fall down to exhaustion?

Alfred is a former member of the British military iirc. He's kept to the military lifestyle of sleeping whenever he can. Sometimes it's just a few minutes between errands and sometimes it's hours in between Bruce's actions. But a lot of his butler persona is faked and he doesn't provide constant service to Bruce. While he keeps up appearances he isn't doing the whole routine now that Batman requires his services. He often hires out for cleaning and kitchen staff and keeps the more delicate rooms and areas cared for himself.
