Several other uniformed guards stand around. A parks employee (different uniform) arrives with a large watering can. He empties the contents into the same trash receptacle.
A cargo van stops in front of this scene. It has been pushing an orange traffic cone lodged under its front fender. Although the van is obstructing traffic, the driver remains in the driver seat checking his phone before he gets out to remove the cone.
The parks employee removes the plastic inner receptacle from the metal can that contains it. He lifts it high to clear the metal can then lets it fall hard on the sidewalk. This causes water to splash high in the air and land on some passers by. They stop, startled, and look around to determine the source of the water.
The security guards leave as a group, talking and laughing amongst themselves. Another parks employee arrives with a broom and dust pan and he and the other parks employee sweep some wet trash off the sidewalk and return it to the trash receptacle.
They walk away together and life along the sidewalk returns to normal
