So I am a student, I dont have a lot of money and I barely order food I usually make it myself. Sometimes though I would like to order food. The place I order from take a delivery fee and I end up paying a lot for not too much food. AITA for not tipping the delivery guy if I paid for everything with my card?

I don't know how much you usually tip in the US but in my country its 10%. When I pay with cash I obviously give a tip when I get my change. It's just absurd that I end up paying 19$ for my ramen noodles.
