I am planning to fly from India to Europe this weekend for a one week holiday. While departing from India, I'll have the Indian currency (INR) which I'll need to pay for things like taxi charges, some snacks at the airport. Now I'll need some small amount of INR during my return to India as well (again for small expenses like taxi charges, snacks, etc)
My question is can I carry the INR (very small amount like 3000 INR..approx 30-40 Euros) while flying to Europe (as I'll need them on returning to India)
