The place I work out is fairly good about them, they said if I get sleeves done in the future I can but I just have to wear a long sleeved shirt which seems pretty good to me! And they don’t mind peirceings as long as they are not too extreme, as for hair a little more strict.
But hell im pleased as they no full well of my future plans and as long as I keep them discreet they have pretty much told me they don’t mind.
Not sure how body mod friendly they are to others though….
