Place this clip right as someone is being shown out of the scene, then follow it with no no wait wait as they protest, and finish with the discord disconnect sound to close the bit.
关于此声音
A fifteen second voice clip of someone politely asking 'scuse me, could you please leave' in a calm but firm tone. It feels awkward and slightly exasperated, like that uncomfortable moment when politeness is running out but you still want to sound reasonable rather than rude.
