Most of the lobby was dry except for this one spot by the elevator. There was a sign "wet floor" by the door where it was wet but not by the elevator or anywhere else in the lobby. It was an isolated patch of water (probably from either spill or melted snow) that they did not seem to have mopped properly. My mistake is probably that I did not take a photo of the surface but I was taking care of my wife. I guess the fact that it was negligence could be inferred from the fact that now they have special mats to prevent exactly what happened.

The front desk staff saw what happened because they looked at us and just did not acknowledge anything until I yelled for help and manager. It was really bizarre b/c we crossed the eyes and they they just went back to chatting with each other as if nothing happened as my wife was sobbing on the floor. Honestly it felt so weird that I initially did not ask for help b/c it was kind of obvious to me.
