A man followed me to my car and tried to get my attention at night, while his girlfriend was in the store

I'm a 23 year old female and I work as a store manager in a convenience store. We are 24 hour store, so we are open every hour of the day, every day of the year. <br><br>When I was in the store one night, around 3 am, a man and a woman came in the store. The man had left the store and had walked to his car, which was parked next to our employee parking, which is where we park our cars when we are working at the store. Now we don't usually have customers parking in that parking area, it's more used by the employees of the store. <br><br>A couple of minutes after he had left the store, his girlfriend left the store. She walked to their car, which was parked on the other side of the building, she got in the car and shut the door. <br><br>About 3-4 minutes after she got in the car, I had to go grab something from my car. As I was walking towards the parking area, where his car was parked, he looked at me and tried to get my attention.<br><br>He was just sitting in the car, alone, waiting for his girlfriend to come out of the store, but yet he was looking at me, and trying to make eye contact and get my attention. I don't know what he wanted from me, I ignore him and walked to my car. <br><br>When I walked to my car, he still sat in his car, he was still looking at me weirdly, and I kind of felt unsafe, so I quickly got what I had to get from my car and walked back to the store. <br><br>As I walked in the store, his girlfriend was leaving the store. I don't know what they were doing, but I just know that I felt uncomfortable and unsafe when he was looking at me like that. <br><br>Also, I don't know what he was planning to do to me, but I hope that he won't do that to any other people.
