Lab

Garry waltzed into the lab.

As in walked not danced.

He was there because he was wearing a lab coat.

Not because he was a scientist or anything like that.

There was no reason for Garry be there.

It is simply that he wanted to be.

This explains why he put on the lab coat and walked in.

No one questioned him because of the coat.

He fiddled with a Bunsen burner.

Flirted with one of the other scientists.

It didn't go anywhere and he left.
