I think i've grew tired on giving people lifts in the car. It's not so much on the petrol or the time, but i am pissed and tired at all the dirt/dust/stones/shit that are brought into the car. Even though i am not exactly the cleanest guy around, and dust is omnipresent, but i do clean the car and i'm anal when the car gets too dirty.
It's bad when the carpet is stuck with small stones unreachable by fingers. Actually i am angry that they are like sitting in the car but they don't bother maintaining it. LIke the carpet cover is always pushed to the front resulting it being bent when they get out of the car. Seriously i have no qualms about giving anyone a lift, but please respect the car, especially if you are taking it everyday.
I swear, the next new car i get, only family members, girlfriend and close friends who appreciate and respect the car and it's cleanliness are allowed on it.
