Relationship Advice

My friend’s 27th birthday is coming up and I have no idea what to get him! His schedule is unpredictable, and he’s usually either working or sleeping, so taking him somewhere or buying him tickets to an event is out of the question. Here’s the info that I’m working off of right now: He works nights, and when he isn’t at work he’s at home relaxing (but being bored). I was thinking it could be something he’ll use in his car (he’s a security guard so he patrols all night) or something to help him relax or have fun when he’s at home. If you have any ideas (nothing romantic or intimate) it would help me greatly. I feel bad because he’s tired and grouchy and having a rough few months, so I’d like to cheer him up. Thank you in advance!
