Is it not an issue if we don't get our biometrics completed at the location they made our appointment at?

A lot of people are saying that the location I got sent to is strict and has been turning people away when they try to walk in and there's another center that people have been lucky about walking in that's close to me, but it's not the location mentioned on my biometric appointment sheet. I'm leaving work to get this done, so I want to do what's more efficient.
