is the do not disturb technology

most places have little door handle signs. those arent any good

some have do not disturb on one side and hey please come in on the other

those are the worst. sometimes you accidentally are showing the wrong side. or jokestersll flip em

the best technology involves the sign being part of the door. like a slider. or a lock.

like maybe if you put the deadlock on the door a little sign is revealed saying dont disturb

cuz maybe you have the deadlock on cuz you were on a party bus all night

and daylight savings has suddenly become your frienemy.
