Having friends in your job is good, but you got to remember that you got the job to get money not to make friends. Its fun getting along with co-workers but you have to have a limit, its important to get the job done so you wont get written up or be noticed. Having any interactions with co-workers can have good sides and bad sides. Bad consequences are like drama with co-workers and even fights. Good ones can be like creating a good friendship with someone, but always have in mind you have to get your job done first.
