to be honest your previous career is not particularly important. I know a guy who has just gone from a desk job out to Flight Training Europe to train as a pilot. The job you mention sounds good as a fairly common question at interview is something like, "tell me about a time you had to use your communication skills to resolve a problem." The job would certainly show that you have the ability to work under pressure. Perhaps find a part time job washing aircraft or even volunteering at your local flying club to prove your passion for aviation.
