With his military background, I don't see why he couldn't pass that off as a quirk of his time and soldierly aspect. A stern man, with a background in very stern matters, I think his preference could bother some, while appealing to others. If he knows the rest of his bag, then he should be able to blend in fine with most people accepting the eccentricities of his character to come from prolonged time abroad.
