<human>: Can you provide a brief overview of the text?

So when he first told me the story I laughed pretty hard about it until he got to part where he was fired. A week ago today he was on break and was just sitting by himself eating when his manager gave him a dollar and said he needs to give it to some other girl at work. So after he's done eating he goes up to the girl and she is busy making pizzas so her hands are covered in dough and stuff. He gently taps the dollar into her front pocket and jokingly says "last night was great." Everyone laughed thought it was funny even the girl did. Only problem is that my friend is 19 and the girl was 16. The rest of the day goes by and nothing. All of Saturday goes by and nothing. On his break on Sunday another manager comes up to him and says I need to talk to you. He goes to her office and she asks him what happened on Friday. He says he has no idea what she's talking about. His manager says that the girls parents contacted her and wanted him fired because of sexual harassment of a minor. He's worried that even though he was fired that the family could still take legal action. How worried should he be?
<bot>: Friend was fired for giving a minor a dollar and saying "Last night was great" Can legal action be taken place?
