This question is really bothering me. Can anyone tell me what possible lawsuit or court action could be?

Minh Lefrancois: Assuming the original restaurant names were not essential to the pun or wordplay, he is at best an opportunist and at worst risks being found liable for abuse of process, filing a baseless complaint and being liable for the town's legal fees and costs.

Samara Siewers: opportunist....the defense to a slander suit is the truth..

Maurice Breuning: Well he could be held liable for telling the whole town that this person spit in the drinks. Also it could be considered a defamation of character for La Poule Au Pot because they did after all take immediate action when they found out the employee was performing this misconduct. Also, why did he take them to court, you didn't say this, and it seems to me that this company has a counter suit against him.
