This is why companies have cheap toilet paper by the way. Not because they necessarily hate their employees, but because it would get stolen and they'd need three times as much.
Also one of the reasons why the huge rolls exist like you see at airports: impractical to use at home.
Depending on the bathroom, some universities have decent TP. I'd say research buildings that you don't need card access to get in. Most of those I've worked at seem to be decent.
