There's a way to get customer service

I was at the electronics department of the supermarket near Casa K.  I noticed this bald headed man screaming at the top of his lungs.  He noticed me, said "hello" and carried on with what I was quickly classifying as caterwauling.  I didn't know why he was doing this.  I was hoping he could stop so I could look for my hdmi cable in peace.  But he persisted in screaming, presumably, because he wanted to be served by someone in the electronics department.  I noticed some clerks looking at him but not giving him any assistance.

Eventually, a store staff person, who looked to be senior in responsibility, dealt with the customer.
