The OP has good advice. Time at Maccas is as irrelevant as the fact that you were in Girl Guides as a teenager.
Stick to RELEVANT aviation experience. Time on the hangar floor spinning spanners would probably be of interest, time sweeping the floor less so. Mention that at the interview, if you get that far. A succinct cv will help you get that far; four pages of bull**** will guarantee that you don't.
