Find it strange the club are deciding to have differnt levels of acceptable behaviour in different areas. The south end of the east would be good to have banter with away fans not zero tolerance!!
i would guess the zero tolerance is for the family section of the east stand. As for the rest of the east stand i dont think it will be any different from the rest of the stadium, for cup games the block at the south end will be away fans and i think most of the pay on day fans will be in east...
