<human>: Can you provide a brief rundown of the text in within 3 sentences?

So, a couple years back... I was at a Shell station buying some snack. Probably one of those cheap cheese danishes. Anyway, this Shell station has historically been occupied by a grumpy old India man with a mustache. Just not a warm person. 

But this day was different. There was a thin, hairless black guy behind the counter. As I'm looking for my snack, I already hear him having a very cheerful conversation with another customer. Anyway... I have acquired my danish, and as I step up to the register, I notice a two dollar bills folded up on the floor. Being a nice person, I pick it up and ask if someone dropped it. There's another customer standing nearby, but nobody claims it. Before I say anything else, the cashier says "Hey man, it's yours now." He says this in the warmest, friendliest voice this side of Morgan Freeman.

Now, I'm not one to take money like that. Someone clearly lost this money. I offer to leave it on the counter in case someone runs back in. But this cashier insists I take it. I go ahead and grab my snack (already paid for when I picked up the $), and as I walk out I say something along the lines of "Eh, I'm too broke to argue." 

He smiles the biggest smile and says "Hey man, ain't we all?" 

That was a good day. I'm still astounded when I meet people like him who have the shittiest, most menial jobs that subject them to all sorts of assholes and the like, and they still have the sunniest disposition and attitude towards others and life in general. Much less one who turns down money, even small bits. They deserve applause.
<bot>: Cashier in a gas station remains friendliest guy ever despite working in gas station, I make 2 dollars and am a happier person as a result.
