sorry guys, but there's no way you can defend a bike shop for screwing this one up.
there's no excuse for such poor service, and there's no excuse for not making it right.
shop owner should have immediately refunded the service fee and offered to redo the
work himself (or senior mechanic).
.
those of you who want to go the 'tangible loss' route........provide an itemized bill.
you spent an hour pushing your bike back to the trailhead, followed by a taxi back
to town, plus additional time and expense coming back to the shop. jeepers, looks
like the shop owes you money now.
