I'm not sure about petrol etc unless it's a regular commitment to eg a weekly granny run of several miles or if granny is on a strict budget.
There are things we do for our grandchildren because we cherish the relationship our time together brings.
It can cost me an arm and a leg to do some granny duties because Rosie has to go into kennels if I am away overnight so that's £30 plus my petrol or train fare. I could choose not to but would miss out on the time with my GC.
I am more concerned about the "critical" OP's daughter whose attitude seems to be rubbing off on GD if she is as stroppy as you suggest. Sometimes these AC forget who brought them up! Remind her who potty trained her or taught her how to use a fork and spoon 
Presumably she survived your upbringing.
You do sound as if they potentially intimidate you and would urge you to stick to "Granny's rules at Granny's house" and if GD is stroppy, then no Brownies or no TV or no treats. Or even no visits. Its not tough love just love!
