There's a lot of conspiracy theories going around on this win. That's all they are... theories. If this jackpot was one of the smaller ones, none of this hoopla would have even come about.
As to knowing the clerks and managers, I know them and they know me, but only on sight and NOT by name. I, along with the vast majority of people, are not on a first name basis, nor do they know the names except from the clerk's nametag IF they have one. This is especially so in cities and burbs at busy convenience stores.
In this instance, the manager recognized the photo of the winner as a regular customer and no more. Just like the clerk at the Valero I see everytime I buy my tickets there. He would not know my name, especially since I only pay cash, but he'd sure recognize my photo as a regular customer. He does not have a nametag, so I do not know his name, but I'd recognize him in a photo. He's much too busy working to stop and chit-chat with customers and learn their names. And I'm much too busy with life than to make small talk with convenience store clerks at convenience stores I stop at because they are conveniently fast to get in and out.
I never lost my dignity over this story or anything else. Not sure how dignity got involved, or that you lost yours.
