Would you pull up outside Kwik fit and ask to borrow their tools to fix your car?
Why do people keep using pointless and irrelevant comparisons/scenarios? How about a better comparison, like you’ve just spent money at Kwkfix, and are about to leave, when you notice a numberplate screw is loose. Would it be such a big deal to ask to borrow a screwdriver for a few seconds? No. And this is the sort of situation the OP was in.[/quote]
Sorry, still does not compare.
The OP had issues with his drivetrain, not a loose bottle cage.
If you were at Kwik fit and just had a new battery fitted. Then discovered you had a flat, a spare tyre and jack, but no wheel nut wrench.
You are going to take the tyre away to be repaired as you have a mate that will plug it for you.
Would you then ask to borrow the tool you need and jack up your car in the Kwik fit car park?
