Point to Ponder

Have you ever wondered why, the coin return slots in vending machines are always so small? I have particularly small hands with particularly small fingers, and im having some difficulty putting my index and middle fingers into that small hole in my attempt to recover the change.

its not that the machine is so complex that the rest of the space is occupied by compplex-machinary, and, if im not mistaken, to cut a bigger hole = less materials needed? or are they not expecting a big number of coins coming out of that hole? certainly that cant be right because of thats the case, why allow notes as big as $10 to go in the payment chute? $10 to buy a $2 drink, thats gonna be a lot of coins, especially so if its all silvers and no golds.

OR? could it be, its to stop fat people with obscenely fat fingers from getting their change back? thats cruel...
