Therapist cancelled session due to ‘overindulging’ the night before. How do you approach this?

You are a client and your therapist reveals to you that they are too sick to proceed with the session today. They offer another appointment date instead. They also reveal that they’ve had “way too much to drink” the night before and light heartedly joke about “never doing THAT again!” How would you react to that as a client? How do you approach this as someone in the profession as well?

I’ve been in the field for years and this is an absolute first for me. To protect confidentiality, I don’t want to give too many details as to how I came to know of this situation. Thank you!
