This 8/10 chick works with a different company down the hall and we made brief eye contact yesterday passing by each other. Today, I went into her office space and talked for a minute or two to introduce myself and grab the number. There was this other coworker guy working in the office with her and for some reason I bitched out on the digits as it was the 3 of us talking. This was like an hour ago. Should I go back in today or tomorrow. I usually don't fuck up like this anymore but don't want to be the guy who keeps chatting a bunch of times before shooting his shot- thats not my style. Any advice on how to re-initiate here? Just go back and not overthink? I already asked a bit about their company, a bit about mine, made a joke and shook hands with both. So thinking of a decent excuse just to walk into their office again.

UPDATE: went back and got her number.
