I am personally not a big fan of the "healing" one, not because its a bad idea, but because its very easily abuseable in IC situations.

The Food healing on hour tick is already terrible enough, if you have ICly back to back fights. Even if you do not try to abuse it, its very much possible that you just fully heal within the RP. If you now can basically just press a boutton and "Take a service" I fully suspect people argueing that they can do it within those 5 seconds it would take for the next fight.
But I guess it won't really make the situation worse.

I am of the same opinion as Hippie however, I do not feel like those service traits nessecairly need to give you combat advantages either.
