Bingo!!!
Several years ago I went to RS to purchase a cable adapter plug. It was the only place in the area that carried the odd item. It cost a couple of dollars, that was the only thing I was buying, and I had the cash in my hand.
Then came the demands for the name, address, blah blah blah. I stated, "I am paying with cash." (Of course they knew this, as it was not relevant to their nosy questions).
The pimple-faced clerk mumbled something about needing the info for their mailing list. I stated pleasantly but firmly that the cash was legal tender and I was not interested in their mailing list. At this point the jerk could have had bolts popping out of his neck. He started spouting off that HE would get in trouble with his boss if he didn't enter the info in the computer with every sale. IOW his bad attitude was all my fault.
Seeing how steamed this punk became when a customer refused to bow to his demands, I continued to stand politely at the counter with the cash in hand, fully expecting to complete the transaction. He rang it up, snarling at me that I was going to cause him grief with his boss. I could have suggested that he seek employment elsewhere, but he was probably working at the only place that would hire such an insolent loser. Figured that he was future Radio Shack management material.
Never stepped foot in there again. I made sure to tell neighbors and friends about the experience.
