Pjiang, 大俠們, please!

擔心中，剛剛去FEDEX寄走１４０／４８５ concurrent package 回來,
I use Fedex Expree overnigt and the package will be in Texas Service Center by 10:30, July31.

Pjiang, 大俠們: Here is my question?
Is it sure that Texas Service Center will pick up my package in the same day?
I am worried about that, because they collect all the packages in the morning, but my package is arrived by 10:30 AM.

Thanks a lot!
