*OK it may not be a lie but:
My car battery was dead yesterday which is a pain in the arse as it's a 40 minute drive to work.
Asked my DP to ask her brother in law if he could jump start it for me (he is a mechanic and has his own garage, not to mention he has jump started DP's car just a few months ago".
He said he can't jump start it because he has no jump leads.
WTF, how can that be?! I know he has so aibu to be pissed off that he couldnt have just said "no, I can't be bothered" or whatever the reason was.
I know it's not his responsibility and would completely respect any reason he gave, too tired, too busy etc. But come on, I know he has jump leads
