VFR general aviation aircraft inbound to FFC receiving VFR advisories from ZTL is instructed to remain clear of the ATL Class B after hand off to A80 TRACON; reporter questioned ATC coordination/handling.

Narrative

Cruising at 6500 FT inbound direct to FFC airport. I had been worked VFR from all enroute facilities. They handed me off to ATL approach. After second hand off; as I hit the outside ring of the B class airspace; Controller said; 'stay clear of Class B airspace.' In pitch black I scrambled to find the altitude of the sector of the area I was penetrating. I turned 90 degrees from course to maintain clear of the next sector until I could verify altitudes. Descending at quickly as I could to get below controlled airspace; I was distracted from flying the airplane due to the fact that the Controller abandoned me with no warning from my direct track to destination. I did the best I could to avoid Class B by descending. I may have cut through an area of Class B by about 1 mile; but I was below the altitudes at that point; I think. The controllers total disregard for the pilots point of view caused this situation. A low time pilot would have been totally overwhelmed with the quick change of plan. I thought they were working me through the Class B as a VFR transient. More time was needed to plan for this change of heart to fly through his airspace. I think I did not enter any restricted airspace; by altitude. I did cut through an area but was below the altitude restriction. This could have been avoided by either telling me early what his plan was or vectoring me through the airspace as was originally planned.
