A stupid question??

Aya and I decided to get hardwood floors installed. The store we used give us an additional 5% discount if we paid cash. We had to pay 50% upfront, so we went to the bank to get cash. We needed to withdrew $3,000 dollars so we had to talk to a bank teller. While waiting in line, I asked:

Miles: Are there bigger bills than $100?
Aya: No.
Miles: Are you sure? What about big ballers? I mean I don't want to walk around with a costanza wallet with 30 $100 dollar bills. Can't we get 3 $1000 dollar bills?
Aya: They don't make $1000 bills.

By now we reach the teller. I tell Aya, just ask the teller.

Aya: Do you have any bills bigger than $100.
Teller: Umm, nnnoooo.
Aya: I told you dummy they don't have bigger bills. You are so retarded.

So, if I won the super jackpot in vegas they would pay me in $100 dollar bills??? What the hell?
