Assault Incident

This is a long and bizarre story. My dad was in Lowe’s last week picking up a dryer. He was there on Monday to look at the dryer, then back on Tuesday to pick it up. He interacted with the same employee both days, we’ll call him John. It seems like John works the floor but isn’t responsible for any delivery/pick up situations. When my dad went to pick up the dryer on Tuesday, an older lady was the one pushing it out and taking it to my dad. Per my dad, he was about a foot and a half from John, and he said something along the lines of “hey, are you going to help this lady” to John. Not sure how this set John off, but he then physically pushed my dad twice, yelled at him to not whisper in his ear. My dad did not physically do anything back. He tried walking away, John followed my dad around the store calling him a chicken and telling him to meet him outside to fight. The woman who was pushing the dryer was able to get a manager who then intervened. The manager says corporate was made aware, but John is still on the floor working. My dad is not trying to seek anything from this situation. He just doesn’t believe this kid is still allowed to work the floor after the incident. Management is not providing any further information to my dad. We are wondering if they have even alerted corporate to the situation, or hoping my dad just drops it. My dad is a contractor and shops at this Lowe’s multiple times a week. Can anyone shed some insight here??
