Those who do will be severely punished. Like the hospital guy who was caught stilling masks not long ago. Although, I wouldn't be surprised if building services switch to the Bring Your Own Toilet Paper model (BYOTP). Are there printers in the office?
Offices in many older / industrial buildings have a "toilet essentials basket" which includes a bog roll / soap etc. Because management / ownership in many older buildings does not think its an essential service.
