Same. And I work in news media (filming, video editing, and reporting - I interact with people in the public on a daily basis). No one cares anymore; at least, no one worth working for. Even McDonalds lets you have tattoos. Slowly but surely people who have tattoos are becoming the norm, and employers, their peers, are willing to accept it. It’s not 100% there, hell, it’s not 50% there, but it’s growing. My father has over ten tattoos in visible places and has never had a problem getting a job (although he HAS, due to alcohol and drug addiction, had problems KEEPING a job…but that’s another story).
Now, to the OP -
I’m going to do what everyone else has said and say don’t go somewhere if you get a bad vibe. I love my tattooist to pieces; every other tattoo parlor I’ve been to I’ve gotten that creepy vibe from.
As to your No. 2 question, choose any font you like. My tattoo artist can do them from sight, but most places have the transfers, so if you bring it in, they can print it off onto a fake tatoo transfer and put it on you so you can see if it’s to your liking, and then just trace over it. There’s a large selection of free fonts at www.dafont.com.
I’d say you could probably, depending on the intricacy of the font and the dexterity of the tattooist, get it done in one longish session, but that does depend on your individual pain tolerance. A friend of mine got a teensy penguin tattoed on her inner ankle and has no pain tolerance (I’m still wondering why she bothered with a tattoo in the first place, but it did turn out cute) and it took them four hours because every twenty minutes or so she’d need a break. Meanwhile, I in the other chair got my shoulder blade done in about thirty minutes, and it was bigger than hers and filled in.
And just like everyone else said - be prepared to be bitten by the bug. For a while it’ll feel like a bad sunburn, and then you’ll start seeing everything as a possible tattoo. I agree with whoever above said look at it for a month and if you like it, keep it, though - remember that tattoos are PERMANENT. Having a tat about justice is fine and dandy, unless you become a crime boss or something.
