I fell off on the yellow curb between Marche and the south entrance of the 5th St market during lunch time today.

It was raining.The curbs were very slippery. No warning signs found around. I fell on the ground and injured both feet and my knee.

I went to the office and talked to management. The lady there said I am sorry, but did not seem responsive to my suggestion to have a warning sign put on the slippery area.
