One of the idiots that used to work at Creatures got a big feather (it wasn't crappy. She actually spent some money on it) tattoo'd on her neck as soon as she turned 18 and then bitched because she couldn't get a hostess job at any local restaurants.
As I said then, some jobs, appearance matters. Personally, I would be hesitant to hire anyone with tattoo's in really visible locations unless the ink was small and discrete. It does show a real lack of foresight.
I also wouldn't hire a woman with *expletive deleted*it tattoo'd across the top of her cleavage, because that's just trashy.
