It's called The Genovese Effect . When everyone see's something wrong but does nothing about it.
Basically.. It's up to the irrigation guy for the repairs.. It's up to the property manager to get a hold of the irrigation guy on Emergencies ( No one can predict an emergency how can you be there to fix it lol) And it's up to everyday people like the mow and blow's to notify the property managers. Pretty simple really
So in this instance I think it's the blow job guys fault because he couldn't take a single second of extra energy in his life and participate in a good deed. ef that guy i'll punch his face
