Does Jollibee, Mcdonalds and Mang inasal accept 17 year olds

As a student dealing with constant shortages of budget kinda irritates me. Sometimes I have to walk home from school cause I can't keep track of my spending.

It's not just personal needs and it's more on keeping myself motivated by going out but without cash I can't do that. I can't really confirm whether these chains allow 17 year olds online.

And if yes what are the requirements?

So can someone please confirm. Thank you!
