Monthly pass agonies!

As you know, 8 out of 10 people who takes NY train from NJ usually buys a monthly pass. I also do the same! But the only problem with this monthly pass is , I forget to carry the damn thing sometimes because of the last minute hurry.
I am going to explain the three scenarios which happened.

(1) First time,Conductor I told me he was not going to charge the extra 5$ surcharge and instructed me to have the receipt so that I can avoid buying a ticket. I paid 10$ or something on board.

(2) Second time, I was smart enought to have the receipt. The Conductor II didn't even care to see anything and asked me where I was going. Didn't charge me a single penny, How nice?! (Thank you Sir!)

(3) Same day evening, Conductor III saw the receipt and told me 'Where is the pass, this is just a receipt!' I explained the whole situation.. 'she' got irritated , charged me the extra surcharge of 5$ too which added upto 14$ something.
