There’s nothing wrong for you in working while you are fasting. What you do by giving people something to eat in Ramadan does not make you responsible for them. They may have an excuse for not fasting, you never know. Even if they choose not to fast, it is their concern.
Allah the Almighty commands:
“Noone bears the burden of another.” (6:164, 17:15, 35:18, 39:7, 53:38)
There’s nothing in your situation to feel like a hypocrite. On the contrary, your heart being uncomfortable is a proof for you faith. If you were not fasting by believing in the heart that Ramadan is a month for fasting, for worship; you wouldn’t be troubled inside while you come across with non-fasting people. You’d just be ok with it. Being uncomfortable, shows that you have a true faith within you. So rest assured and be positive about your faith.
