Pops: Beauty is in the eye of the beholder

Lattice isn't drop dead gorgeous, but an athletic build on a young thing that wears only trenchcoats over wetsuits draws some gaze no matter what. Combined with a sharp tongue, the inherent mistique of a scavenger and a pretty stubborn will, she's got something there that makes her stand out. She's also got a mean coffee habit and a discerning pallet when it comes to the stuff, so usually operates out of your establishment when she needs to arrange meetings with folk that she's unsure about. So yes to either of your choice.

If Pops has been around as long as we reckon he'll have known Lattices uncle, Red, who adopted her after her parents died and took her under his scavving wing. Dragging a child down to street level was probably just a sign of how much of a piece of work he was, and his eventual death was probably for the best.

That being said, no one really tried to stop him. So ten or twelve years later, where does that leave Pops and Lattice's friendship, if any?

Attractiveness seems like a personal choice, so there's not much for me to add that's not already on my character sheet. I will say that Canary likes being well known and relied upon. So that might make him attractive to those who are into powerful people? Other than that he's just an older pirate who likes to talk.

He doesn't care for coffee since it makes him nervous and twitchy. He's a morning person, so drinking coffee would just be overkill. He likes the smell though, and would help deliver goods to the shop as a favor.

Where is your establishment located? If it's in Canary's holding, Atlas Terminal, Canary would definitely be supportive and friendly. If you are located somewhere else then Pops and Canary would have a more business-like relationship.

'Killer' ain't attractive, in a conventional way, but he's damn handy to have around. His presence alone has quelled a few fights that would have broken out, and he respects the place- he never touches the waitresses, he's polite, and he tips. The one occasion he's had to bring pain, he took it outside.

He's quiet, though, probably not anyone's favourite, but he gets respect in turn.

I'd assume no on both fronts. Eddie and Pops has the same taste in clothes but half of Eddie's face is wrecked. There is also the part where Brainers are known to fuck you in more ways than one. He may be a favorite for his usefulness but he is a shitty image to customers. That doesn't stop him from being the occasional patron.

Goldaline is a regular customer at Pop's place. The first time she was seen in town, she was trading canned goods for some coffee. Now she's totally hooked on the stuff.
In regards to attractiveness, she's got a pretty face if you can get past those black eyes. But still she's only around the 12-14 age range, so hopefully not on anyone's radar yet.
