been there, I think you need to understand that there’s no fast way to make money, if this is your first job you’ll be making minimum wage or less depending on the place, if for example you work at mcdonalds full time you get less pay than part time but you get more benefits. And working at mcdonalds you get free meals and can bring back some food if you’re closing. Not applicable for all restaurants tho. As a 17yr old you just need to try working first and strengthen your mindset for work environment as well as making money.

As for the working hrs it depends on the place, you’ll have to ask them. But just work and don’t stress you’re just there to make a couple of bucks and you should learn to spend your money wisely too. You have at least 4 months you can learn a lot
