car problems again!

i got a brand new battery 3 months ago, which had been checked just before i went on holiday. this didn't stop it from dying on me after just 2 weeks of sitting in the garage. and of course, it actually happened on a day i really needed the car for work (to be fair, though, it had never happened at a critical time before, so i can't really complain...)

anyway, after asking a few friends what they thought the problem could be, i finally took it in to get checked at the garage. and that was just epic. i asked for an MOT with an additional check to see where the leakage could come from. and it was clearly written at the top of the quote i signed. but when i went to pick up my car, and therefore asked if they'd found the problem, they had no idea what i was talking about. i had to re-explain the whole thing and leave the car an extra day. when i eventually got it back, they hadn't found the source of the leakage, but pointed out once more that the battery was under warantee, so even if it did empty out again, i'd still be able to get a new one.

yes, but that doesn't really help me, now, does it? i mean, if this happens again, i'll still first have to find a nice neighbour who has a car and is willing to spent 5 minutes helping me jump start mine. so now i basically have to make sure i drive the car regularly so it doesn't just die on me again.
