I had a positively hilarious interaction when somebody with my name used my personal email address for their retirement fund provider. I received an invitation to a zoom meeting addressed to my personal email account and their work email account. So I went ahead and joined the meeting in progress.

I sat silently for a bit while the financial advisor finished his talking point. Then I spoke up. I don't remember exactly what I said but the other guy with my name sat there with a scared / dumbfounded expression on his face while the financial advisor calmly asked me to leave.

I told him I would leave as soon as they promised to remove my email address.
