Curious sign at the English Babingtons tea room in Rome

Right next to the Spanish stair in Rome, there is the famous ( at least among the Romans) Babingtons, which is an English tea room that have been open since 1893 (not completely sure about the year, but late eighteen something). The place is very nice, and usually a peaceful oasis in the middle of the tourist hell around "Piazza di Spagna". But it will cost you, course this tea place is so very expensive.

But imagine my surprised when I arrived in front of this sign in the mens room ( later I had it verified that there was a similar one on the ladies rooms.)


(Sign says: "Please use waste paper basket under the sink")


What is it exactly I should do in the paper waste basket under the sink. Here I was standing here just wanting to pee, so it would probably not smell to bad if I used the basket, but what if there was another English speaking person that need to go number two - under the sink?!?!

In Italian it says please put the paper in the basket under the sink, but in a small piece of england, you would expect them to use at least a little bit of the overpricing to get their signs translated correctly.

Alone what they earned on the scones we bought, should be enough to make new signs and translations.
