Working at Quickie Burger will offer more events than the Sumnit Market, but they have a dresscode.
The pay at start is similar but you will get some raises.. 9/11 and after the streaking up to 15.
Any streaming seems more profitable, but will need to invest in better equipment to make it really worth..
Videogames skills is the more profitable.. you can bet daily 50 and there're the tournaments in the weekends. (at the Arcade in Town)
In the lounge of the dorm during the day till 10 PM you can play with someone, let them win and probably they will ask for another kind of game.. they will make a bet for 10 bucks!
The Harasser spreading rumors about you.. you can get up to 50 for blowing a stranger (some of them won't pay that much cause they're broken)
Gardening is really limited right now, but also the Greenhouse can be used to gain a bit of extra bucks.
More works will be available in future (need time to write the scenes).
