People who give out minimal amonts of change (Horrible Title, I know)

This something that I really need to address because I don't know if it's just me who feels this way. Most of the time, in any situation, it's usually only me who finds something funny. But I wanna run this by everybody. Okay, so here it is: You're on the road with your dad, maybe going to New Jersey (I don't know why), or Cooper's Town (or is it Coopers Town?). Either way, he sends you into a store to pick up some gum and maybe a pack of smokes (even though your only 8...). So you end up with a laundry list of ten items and he gives you a five dollar bill, and asks for change. And you're like, I don't even have enough for half those things. Of course you probably run out of the store while paying and he gives you one of those grunts/looks, perhaps he thinks you're pocketing the change, and gives one dollar more. I literally have done this four times until I could buy a buttered roll, some water, and a doritos. But the worst is when that five is enough and you come back to the car and your dad, or whoever, has the face that says, "I told ya."
