blimey.
I remember on one of my previous cars. got new tyres at Costco.
They were taking forever and I was watching them stare and the tyre for ages looking all stressed. Then after a long wait said all done mate but couldn't get one of your wheel nuts back on. it must be bent or stripped or something. 'we've tried everything' 'make sure you go to the garage to get it sorted'
drove back home (annoyed) but then was able to put the nut back in by hand then tighten it properly, really have no idea what they were doing.
