Maybe the eyebrow. They grow out sometimes anyway. My brother has had his grow out a couple times, so he stopped getting it re-done. I'd be worried about the lip one damaging his teeth.

I used to work for a fast food outlet (like 9 - 10 years ago now!) and we werent allowed any facial piercings. The only thing they were ok with was ears. They used to ask you to remove eyebrow and lip piercings before work.
