Can I deduct as "supplies" the coffee and snacks that I get for my students? I am a private tutor and I meet my students at coffee shops, I always treat them with snacks

Also I am self employed and tutoring is my main source of income.

Not as supplies, but as "deductible meals" on your Schedule C, and you'll only be able to deduct 50% of these costs.
