Narrative:
On final to sfo runway 28R, the final controller advised me that an air carrier B737 was at my 7 O'clock position, had me in sight, and was not to pass me. At 800 ft AGL, the B737 passed me, missing my B757 by 100 ft vertical and 700 ft horizontal. He then dropped down and landed on sfo runway 28L about 10 seconds before I landed on sfo runway 28R. I did have to take evasive action to the right. All my passenger on the left side and I were very upset. I called sfo tower supervisor. She said that she would look into it, but it was ok for 'a little aircraft to pass a big aircraft' but not vice versa!
