Ok, so what is your advice if I want to start over, what should I prioritize with first? I know maintaining the business, but again how do I recruit people? I try to bribe them with higher salary they still refusing which kinda ridiculous if I should say myself lol.
(I always try to recruit my sister first as a bartender, but it's a struggle. First, the game should generate you an unemployed sister, so if she has a job already, start over again... and again. Next, your first moves should be putting up an ad for bartenders and then finding your sister and offer the job. And save, 'cos 9 times of 10 one of your competitors hires her just before your interview. The umemployed people, who the game creates at the start, are the pool from the other four clubs get their first bartenders.)
Every now and then your sister/daughter send you "a friend" of her, if you have jobs open. It's random, but usually one comes in the first month, then one in every 2-3 month. It's one of the mechanics of the game to help you and to create more and more NPCs.
In every month, some NPCs spawn, depending how many free jobs all the clubs have, most are unemployed. Some of them don't like to work, but most of them do. You should only offer jobs to them, as nobody hops a fresh job (3 month time), and nobody wants to give up their job for your flea-ridden club (e.g. low fame and you swimming in debth).
I did not notice when and how I got the apartment. I want to go Home and sleep in the morning, but I do not have such an option.
The office IS your home. You have to play a long time (1 ingame year, I think), 'till the game offering you to buy an apartment.
How can i get more employees to be receptive to me training them? The majority are 'unwilling' to learn. Do i just have to keep firing them until i get ones willing to learn?
There is 3 possibilites, try to find the one that works. There - as in everything - are same randomness in it, sometimes their skill grows nothing, next time growns more. Patience. Or save-spamming. (Or cheat down their willpower, and then the 3. option usually gives them +10 skill for every training session.

)
Secondly, sort of related. It's hard to find employee models i like, which makes me not want to fire therm. Despite what's pictured on the front page here, 90% of NPC's are fatties. I set the likelihood to be fit at its highest recommended, but that shit didn't work.
It gave me a total of 5 Asian girls. 3 hugely fat, 2 skinny ones; and the hottest Asian girl, was of course, gay, and says she's not attracted to me even though i manually went in and made her bisexual, no matter how high i get her friend score.
Now that if freeking annoying lol.
RNG is a bitch.
Still, you can edit your save, changing the picture set to the one you likes.
For the bixexual one, maybe she like a different type (short is you are tall, long hair if you are bald, same ethnicity if you are white, and so on). You should talk to her and change who she is attract to. To have date, sex, not the first score counted (friend score), but the second one (attraction score).
