Say, what's this crazy fee for sharing that, apparently, some
restaurants charge??

There is this spanish restaurant that charged me some kind of penalty
fee for sharing a pot of seafood paella (or whatever the hell it's
called) with my date who doesn't eat much. The pot of boiled rice and
seafood bits (big deal!), a salad, and two soups was like $30 already,
and the manager charged me like another $6 for sharing! WTF is up with
this??? Is this a very common practice in hoity places?? el senor
claims it's for having to wash the "extra" dishes and ultensils...?how
do you say WTF in espagnol? I dine rather widely and have never heard
of this BS.
