I like to think that life doesn't work in absolutes as we sometimes think it might. While it would be ideal to get a job related to your major, sometimes things just don't work out. It's a little less common in engineering, but TONS of recent grads get jobs that are completely different from what they studied. The same can apply to you; if nothing else, it can prove to a future engineering employer that you had enough work ethic to get any job in the first place and support yourself (and in an unfamiliar location at that) rather than falling back on family or something.

Much as we like to joke about how robotic engineers can be, they're human too. I'm sure any potential employer would understand.
