I agree with all the posters so far.
Civvy Street is different, and you can learn a lot observing from 'street level' for a bit.
Your problem may be getting people to hire you for a 'street level' job with a full Service CV. Try leaving chunks out. Civvy street is well aware of what Service types can do. You may well not get hired if the hirer realises you can do his job better than him.
When the ideal exec job turns up, they just see it as part of a Service ethos to always be in work. I have never had it held against me that I was (briefly) a milkman. Indeed, I arrived at one teaching job where the school on-site transport was an old milk float, and they were desperately grateful that I could drive it!
Good luck!
p.s. try to pick a job that lets you attend interviews easily, like milkman or similar hours jobs.
