Ok.

Let me explain how bars work.

They are generally fairly small and crowded.

There are often a lot of people having conversations with a lot of other people.

You can often hear some, or most of these, depending on where you are sitting.

Overhearing other peoples private conversations, that they are having in a public space, often loudly…

… That is not eavesdropping.

That is existing, in a bar.

Framing this as eavesdropping is absurd.
