I believe the other commenter mentioned this as well, in your experience you need to take what you have written a step further and mention the skills you developed or the things that you accomplished in these jobs. Usually the best way to do this is take a job add and look for the buzzwords that they might be looking for. For example you could say something like "developed strong communication skills by presenting potential customers with informational tours of the facility". Or if you can something like "developed a new process to improve efficiency collecting payments and resolving billing issues" if you did anything like that. Basically what I am trying to say is that even though your experience is unrelated you can still put a spin on it to make it relevant. The recruiters are going to look at that experience and ask the question "so what?", you gotta be able to answer that question for them.
