I can vouch that Walmart has terrible customer service and response to the intercom. Just last Wednesday it took me over 15 min., 4 interactions with Walmart employees (twice with the Asst. Mgr.), two intercom pages, and finally Eeyore showed up so I could pluck a $9.00 headlamp out of the locked case.In the twitter link in the OP, his text is below the videos. About 7 lines from the top he writes that he "yelled"... "Customer assistance needed in sporting goods!"... after hearing that request being ignored 4 times over the intercom.
I can understand, and might have done it myself, him yelling for customer service. I have been known to call the store on the phone to request help while I am standing in the department. I do think, that as an OCer, you should be careful of how you project yourself, and the rest of us. There might have been a better way of voicing his concern.
