Signese

The standards of decent writing.

I agree with Outofin.

國語辭典 says

副 2. 既、已經。通「已」。三國志˙卷二十三˙魏書˙杜襲傳：「吾計以定，卿勿復言。」

The right hand door probably has a broken spring that keeps it from closing all the way. It's standing open a little in the photo. The proprietor wants entering customers to use the left hand door instead, and it's still labeled 拉 in red. I take the meaning of the sign to be sort of "this door broken for use."
