Questions: Guy's Behavior

Hey there! Met a guy at work (same level as me, but in a different department and building). I'm used to guys being straightforward in asking for my number and to go on a date, so this one is throwing me for a loop. On the one hand, he hasn't done any of that, so I can see either cautious (because of work) or disinterest.

On the other hand, he's very regimented when he walks in to work. He walks in, goes in the bathroom, comes out, then makes a right at the turnstile. If I happen to catch him in the parking lot, he goes out of his way to walk me to where I turn to go to my building. We linger and talk, laugh, he'll drop a profound statement, then we go our separate ways.

The convos aren't deep, but they have helped us learn a little about each other. I couldn't tell you how old he is, where he's from, where he worked before our company (I know he's new to us), if he's been married before (he does have a kid), nothing. I have complimented him a couple of times but he hasn't complimented me physically.

I feel like asking him out would answer my questions, but what say you?
