My daughter's MiL, who happens to live in the same village as us, which is approx 20 miles from DD, SiL and 2 DGC, goes once a week to pick up the children from school and nursery, as I do. For any extra trips, such as going to the panto with them at Christmas [a treat from DD and Sil], she always asks for a lift. We don't mind this, as she has less money than we do, but we do object when, as we enter the car park, she remarks on how expensive it is but doesn't offer to pay or contribute and, if we buy ice creams etc at the theatre, she offers the money for hers.
