Why would your boss invite you to a bar on your last day?

I don't know. Maybe because they like you and want to show there are no bad feelings.

Or, because it would no longer be sexual harassment.

Because bars are usually the last place you are seen before you disappear! 😂

Getting ready to hook up with you

IDK but I wouldn't go anyway 😂

My boss took me to the bar across the street on my last day for some drinks. I enjoyed it.

Depends, retired or terminated?

To celebrate the good times

Why not.

I would go and listen to his lies.

Either a polite way of thanking you for your service or perhaps hitting on you (?)

Farewell. It's a respect thing.
