Swiggy — not giving appropriate amount of change of money

Whenever any swiggy delivery guy comes they never have change with them. Even if it's a big amount or small amount we have to only give the change.
Everytime that is not possible. They giving me back 30 rs or me giving them 166 rs what is more sensible?
And plus they have no manners to talk.
Even if we mention while ordering in the comments that i need extra change they do not bring it.
