No Good Deed Goes Unpunished.

Some years back I was fueling my cab at a gas bar,it was the end of another long shift and it was pouring rain.
I was approached by a guy who wanted a ride,he was just going a couple of miles down the road.
I told him "sorry pal,I'm done for the day,but I can radio in and get you another cab",he pleaded "oh come on man I'm not going that far, and I'm already soaking wet".
So being the nice guy that  I am ,I said "oh all right get in out of the rain,I'll go pay for my fuel and then I'll run you down the road".
I remember it was $50.00 for the fuel (ouch) and I quickly went into the store handed the clerk a fifty dollar bill,got a receipt and was back to the cab in 3 minutes.
As we were driving down the road this guy was asking me if the company provided us with a cash float,I said no the company does not provide us with anything,but now I was suspicious as to why he would ask that,but I was tired and just dismissed it.
He wanted out in a school parking lot which again raised a flag with me,so after he got out and started walking down the street I checked my duffel bag, which is where I kept a Tupperware container full of coin change.
The container with about $30.00 worth of coins in it was gone,"son of a bitch I thought, that prick just ripped me off " and considering the short time I was out of the cab at the gas bar,he was damn quick about it.
So off down the street I go in hot pursuit of  this ungrateful  thieving asshole.
He was about half way down the street by this time, walking along the sidewalk like he was just out for a freak'in stroll.
I pulled in to the first driveway past him, blocking his path, and confronted him about the missing money.
He of course denied any knowledge of the money container,and was about to walk around my cab,when I noticed a large bulge in the lower pocket of his cargo pants.
Whats that in your pocket I asked him,"its nothing man" he replied,so I told him "listen asshole give it up, or I'll have the cop's down here to pat you down".
He gave me this stupid grin and said "okay man I'm sorry" as he reached down unsnapped the pocket and handed me my container.
As I took back the money I asked him "what the fuck pal",I do you a favor and you rip me off ?
At this he reaches in my window with an open hand and wants to shake my hand "saying no hard feeling's eh".
Your a real piece of work I told him,"now get your hand out of my face and get lost".
I backed out of the driveway and drove away shaking my head,thinking its true...good guys do finish last.
