Let's just say that "someone" was driving around in a big town that just recently has opened a whole bunch of new toll roads. And this someone was driving around in said town with absolutely no clue where she (or he since this is hypothetical) is and only a vague idea of how to get where she/he wants. And let's say that without realizing it, this person accidentally gets on a toll road. And when approaching the toll gate this person realizes "HOLY SHIT, I DON"T HAVE ANY FRIGGIN CASH!!!"
So, this person frantically searches the floorboards and the bottom of her (okay apparently this is a female hypothetical person) purse for change to pay this toll and realizes that there is no way in hell she is going to come up with enough pennies to pay for this.
Now, just supposing, this person drives up to the toll guard person and asks to use debit or credit or hell even a check. This person then goes on to explain that she didn't mean to get on this toll road and really isn't sure how it happened and since it wasn't planned she didn't get any cash. And then she babbles incoherently all the while more cars are piling up behind her and finally the poor toll booth operator just tells her to just go, don't worry about. So she thanks him profusely and babbles for another minute or so while this poor man just wants her to get the hell out of his lane.
