<human>: So this happened yesterday, I was on my way back from school, in the public bus. There's a bus card system where in you tap your card on to the machine and get in the bus. 

So I do that, and take a seat, and now that my phone has no charge, I'm sitting idly since I've nothing to do. In all this boredom I start to take my bus card and keep swiping it on the glass (no windows, the top of the bus is entirely covered with glass), sometimes blocking the sunlight from my eye (It was kind of fun?), suddenly my finger slips and I loose grip on my card. Normally, there is a plastic extension below the glass (at my elbow level) where people keep their hands while sitting, so, logically it should "fall" there and shouldn't be much of a deal. Turns out there was this small cavity between the plastic extension and the glass. Whoosh, fate had it. My card went between the glass and the plastic. And no way to remove it (That thing was fitted with six screws).

The lady behind me starts giggling, not much of a problem for me, but what I begin to worry about is if somebody asks me for my bus card (random checks happen once in a while): "Uh, sir, I was playing with my bus card and it fell in there". Thankfully got out, but the card didn't.

Give me the gist of the text in a nutshell
<bot>: Got into a bus, played with the bus card, bus card got into a cavity between the glass and the seat. Was really worried about a random check.
