If a good friend came to you to say that he/she had a problem with his/her tyre...it was deflated cos there was a slow puncture - and he/she didn't have a clue as to what to do...what would you do?
Would you:-
A. Do nothing?
B. Offer to blow the tyre up cos you have the means and know-how that he/she lacks?
C. Blow the tyre up and then pay for a replacement tyre?
