why do people keep dropping off their stuff with dealers having no idea what they will be billed and then get all pissed about it?
written estimate.
signature required if over 'X' amount. verbal approval by phone if over 'Y' amount.
it's not that difficult and any reputable shop will do it with you.
If someone posted up about home repairs; having a crew come in and do work with zero idea how much it would cost; and then getting raked over the coals, we'd have a field day giving them shit. But when it comes to bikes we all say 'oh that's horrible'
That would just be too simple and reasonable.
