I have the wallet, paper, pencil/marker, work, black tape, glue, bucket of water, stick from mop, mop head and those mysterious sticks. I have no clue what to do next LOL.
Enter the room on the right and talk to Barney. Talk about all security issues.
One more little hint please? I still can't figure out what exactly it is I need to do next.
There's much more to do in the security room:

From the shelf take the BELL and the COLORANT. Look at the bell to find the magnet on the back.
Besides, have you checked out your wallet yet?
I have checked my wallet and I have the credit card. I also got the confession for Milton and gave him the work. Still not sure what to do next.
Now you need to make sure no one notices that you're gone: find replacement.

Use the mop in your inventory to take the stick from the cloth and put the cloth in the bucket with water to make it soft. Go to the cleaning room next to your office and empty the bucket.
Then go to your own office and create a look-a-like.

Use the stick on the chair, put the bucket on as head and add the cloth as wig.
Since it doesn't look entirely:

Use the colorant on the cloth to dye it black and use the pencil marker on the bucket to create a face. Finally use the glue from your inventory on the stick in the chair add the two smaller sticks from your inventory to serve as arms.
