My coffee shop is full, and I’m by myself, but I’d be happy to share the table if there a mechanism to signal that. They should have create a little sign that you could put in your empty spot, letting others know you have a seat free. Maybe one sign could say, “Seat free, I need to work and can’t talk.” “Seat free, I’m open to chat or work.”
