On AA 2339 right now and someone boarded with a so called service dog that immediately started yipping at passengers. Flight attendant took one look, exchanged a glance with the rest of the crew, and within five minutes a few employees came on and escorted the passenger and dog off.
No drama, no delay, just calm and professional teamwork. Honestly refreshing to see it handled quickly instead of everyone pretending not to notice.
Huge props to the crew for not letting it slide and keeping things moving.
