1. have an argument or get into trouble with somebody/something
have a run-in with the police
This expression can be used in a social or professional setting and implies a negative interaction with somebody, or some type of authority, such as the police. This usually takes the form of an argument or disagreement, but unlike other expressions in that category, such as 'at each other's throats,' this phrase is used for less serious confrontations. In social situations, you would use the term to describe an argument with a stranger or acquaintance rather than a friend. In a professional situation, it is not unusual to have a run-in with a customer, co-worker, or a manager/boss.
