It is never too late. Any on-the-job experience is valuable, even if it is a lousy job. Learning to work with others, learning the dynamics of a business, learn what is important to your bosses, I can go on and on. Same principles apply to any company and when you master them sooner or later you can take advantage of it and impress your future manager when it really counts - on your resume, during the interview, and when you are trying to accomplish goals in your future job. I still benefit from the skills I gained doing hard laborious work, working with people with all kinds of backgrounds.
Go for it! Good luck.
