Script: Don't upset the applecart

The expression ‘Don’t upset the apple cart’ means ‘Don’t cause trouble by spoiling someone’s plans’ If you think that someone is going to do something to stop things running smoothly, tell them not to upset the apple cart. Then they might think about the consequences of what they were about to do. Listen to these two conversations. Penny is talking to her friend Rose, and Jon is talking to Len, the manager of the amateur local football team that Jon plays for.
