I just got back from Halle
Didn't see Giova play (he lost already in Q and still was there at least until yesterday), but I did see him walking by and asked him to sign my flag.
He was really nice and somewhat surprised, because he asked "where'd you get this?" with a big smile on his face. I answered internet... apparently Giova doesn't know you can buy almost everything on line
He did his best on the autograph, it's really nice. Just a little stupid of me to have it upside down, so he signed on the wrong side
