Robbing bees is always a problem when flows slow or stop. 
After a rain is always a problem.

Obviously the supers were too  close but robbing can happen at even greater distance.

Once we had bees from a couple hundred hives robbing in the honey house.
a side door was left open while the guys went to lunch.

The only solution was wait till sunset and open the doors.
I even turned the bug zappers off.

Of course the problem was blamed on me for not moving the hives to a holding yard.

My wife asked what I was going to do so I fired the person which left the door open. 
He laughed as I fire Aaron a couple times a week. 

Gets his attention but he knows after 20 years his job is secure.

I have worked long days in bee yards with robbing bees but does not make for pleasant 
beekeeping. 

I am glad for me those days are over. 

In larger operations work goes everyday except in downpours.

Heat and humidity is a bigger concern than angry bees in commercial beekeeping

Back breaking work plus boring work is a bigger problem than angry bees.
