Mind Your Own Beeswax!

So, I go to the gas station today. I'm a little bit frustrated when I try to use my new debit card in the pay at the pump and it doesn't work. eh, whatever, I got time. So, I go in and the lady says that sometimes debit cards won't work because it charges as a credit card either way, so if your card is set up as debit...something or other.
I give her the card and go back to the car and fill up. When I go back in to pay (where they run the card there) the man working with her is handling the transaction. OK. So then the card is declined (I just activated it yesterday, so there is some kind of issue). I'm getting agitated. So I tell her "Here, just put it on this card, I just would rather have used the debit. But it's new and I guess there is some kind of issue."
Then the man says, "WELL, did you know that in February, all the credit card interest rates are going to double?!!! yeah, that's because THAT president that EVERYONE IN THE COUNTRY wanted is going to cause that with ...." he said some more very negative comments. I wish I would have said, "hey. Obama is my dad!"
I don't care AT ALL what his opinion of the president is. And it's not his business what mine is. But what I especially don't like is that I am purchasing something in your store. If you want to discuss something other than that, maybe you could talk about the lovely day instead of risking offending me when you have NO idea what my feelings are about the president and don't know that he ISN'T my dad/uncle/facebook friend, etc.

Just give me my card back. jerk.
