Heine keeps his gun pointed at the floor, one hand on the grip and the other bracing the barrel, stance relaxed and ready. He's fine with Jennifer doing the whole hold-up part, and just stands by as they secure the building. The windows are small enough that it'd be hard for anyone to see what's happening inside the building unless they were directly in front of them, but they have to get things done quickly.

The woman trying to slip past them isn't exactly conducive to that, though, and at Jennifer's request (of sorts), Heine takes two steps to close the distance and strikes her across the shoulders with the butt of the rifle, sending her to her knees, shouting in pain.

He might not have had to hit so hard. Heine keeps his gun pointed at her and looks back to Jennifer. "Under the counter. Give her the safe combination." The last part, he directs at the shop owner, who is mouthing words desperately at his daughter, probably trying to convince her to not resist.
