It isn't the same, though. As welder, she can work a stable job in an established business, and while she wouldn't be making art or murder-chassis, she can get paid a lot more than as barista, and might even be able to negotiate better terms. (I'm still a little disturbed over how easy she could get fired, without any kind of security or compensation or anything, and apparently she didn't get paid holidays as assistant manager. And it was only because Dora didn't file the paperwork right away that her healthcare still covered her - that's just horrible.) And it would be a job doing what she's good at - she might be good at making coffee, but her interaction with customers would be very out of place at any other place than CoD.
On another note: That one felt very classic - funny and serious at once, driving the plot forward, with a punchline provided by our favourite seabiscuit. Awesome!
Of course it's not the same, but Faye needs to learn to modify her behavior, anyway. There's sass and then there's assault. Faye tends to live near the latter most of the time. But, setting that aside, we know Faye has skills because she's an artist, but welding a sculpture and welding, say, a pressure vessel or load bearing member (cue Pintsize) is a whole different animal. She may not be qualified to do that as work.
Also, I've done a lot of writing, professionally. You know what kills the desire to be creative? Using your creative skill to do non-creative things. After a long day of churning text for a quality management system, the last thing I wanted to see was a keyboard.
All that said, I'm not saying Faye should run off to the Bakery, right now. That would be foolish. Marten's given her time, and she should use it intelligently to find work that doesn't interfere with her creativity (Obviously working in a coffee shop was doing that, for some reason). But going to work in another coffee shop isn't doom for her.
Throwing everything on the hope of a creative endeavor is super risky. Trying to join a certified trade is a huge time sink, and costs money. Given her current lack of income, that's another problem.
Obviously, this a fictional universe with strong AI, and kinetic scorn. The issues can be papered over. All I'm saying is that working in a coffee shop would not be bad for Faye. Not bad needn't equal best. I mean, she could become President, or CEO of Apple, or an astronaut. She won't, but it is fiction, so she could. Those would pay better than welding. Why not aim high?
Jim has plenty of reason not to hire her, anyway. That is, he's familiar with her. At the same time, she's been a positive influence on Sam, and she's half the reason for a successful partnership between the Bakery and Coffee of Doom. Storywise, Faye working there, and actually using the semi-familiar job as a means of expanding her life outside of work is just good for the comic, and potentially good for Faye.
I'm not arguing that these things must occur, or the comic is bad. I'm just disagreeing with the idea that not being bold is bad for a person in Faye's position. Trying to weld professionally or as an artist would be bold and super stressful. I'm an artist who is, literally, giving it away free and I'm stressed right the hell out because it was bold move. I have depression and abandonment issues, and if I had a drinking problem, I'd be hammered. As it is, I have a procrastination problem, which you can see I indulge in. This post ain't payin' no bills.
Tony Stark was right when he told JARVIS, sometimes you've got to run before you can walk. But to borrow another line from that movie (paraphrased) Faye is not Tony Stark.
(Get Raven and Emily together to work on the hardware and software inside Faye-built chassis, and you're on to something that will either save the world, or destroy it.)
