Lazy Magnolia

So, I booked a vacation through booking.com and decided to add a rental car too. I called to verify that my rental car was still secure and what my total would be. Representative Raul explained it would be $258 plus tax and nothing extra. I go to the airport to pickup and this other Representative Ray Atkins was very rude, unprofessional, and biased. I get to the counter to check in and he asked me was I paying with a credit card. I said yes and then he asked was I getting insurance with the car I said no because I have my own insurance. I give him my credit card and he's looking at it front to back with a disfigured facial expression like a black person can't be legit with a credit card. So I'm already feeling a certain way, but I kept my composure. So he swipes my card and it declines. I said I forgot I had it locked. I go in my app and unlock it. Keep in my mind that he never tells me that it is an extra $200 security deposit.(I'm assuming that because I declined their insurance and told him I had my own) So it declines again. I'm like what's going on? Then he tells me, Oh it's $458. But I only had a $300 credit limit. I did have the money on my debit card. He tells me you can't use it because you don't have a booked flight. The only way we can process your debit card is through a credit check. So, I went to ask the other Representative next to him (an older white lady) and she was even rude and refused to get my debit card to run the credit check as I'm pulling it out my wallet. Claiming it would be a long process. I was very disappointed on how I was treated and felt low as a black man. This was my first time being at this airport or any airport because I have never been on a plane. But I would not ever come back to this airport!!!!!!!!!!
