Something else. This was one of the OP's first posts on this forum. So they were either lurking for a while or looked for a platform to vent on after the fact.
If after reviewing the guidelines for the shop, theycould have asked about not having a car here. Or if there was a question about using a car service, they should have contacted the scheduler and asked if that was acceptable or not.,
They might have found out from the community or scheduler that driving and parking a car was considered part of the shop.
But I still believe they should have been paid a decreased fee. If nothing else just reimbursement for their expenses.
