It takes two weeks to pay your check

I search in the Internet a lot to find a replacement for my car. I wanted to buy a car to give it to Ella for these two weeks that I was going to travel to LA. I found another car similar to my previous car that was a little bit more expensive than the car I bought. I went to the bank to cash my check, but the bank told me, "We can't give you any money now. Since the check's amount is high, you need to wait to get it into your account. It takes about two week. You will receive about 5000$ the next week, and another 5000$ the week after that."

I didn't know that it took time to cash a check in the US. So, I canceled the buying car process. I took me 5 hours today to go to Time Warner Cable center and give their modem back. It was very far, and I didn't want to ask my friends to spend their time for me.
