It is often noisy in restaurants. Bose or one of their competitors should invent a noise cancelling device that makes it less noisy. They have done it with headphones.

I’m visualizing an Alexa looking pod on the table that cancels noise from everyone outside of a six foot circle. So that loud man at the next table doesn’t disrupt your dinner.
