<human>: Provide a brief overview of the text.

I work (used to work) at a historical coin shop that takes itself VERY seriously. But, being the new guy (not to mentioned the youngest one on staff by about 30 years), I was given a job in the back office opening coin binder and dumping out the coins. My boss gave me a dull butter knife to use for cutting through the cardboard, and I put up with it for about 2 weeks. And then I had a "fuck this"/lightbulb moment, and decided to bring in my brand-spanking-new switchblade to open the binders with. Just today I happen to be working the front desk, and a customer comes up with a binder full of valuable early 1800s coins. He asks that I take one out and tell him a bit about on e of the coins, and I see the perfect opportunity to use my gorgeous switchblade. I flick it open in front of him, inspiring a gasp of awe (or terror), from the customer, and proceed to slice through his binder and into my finger. The blade went about 2/3 of an inch into the fleshy part of my thumb. I pull the blade out, and blood begins dribbling down my arm, onto his binder, and all the fuck over his precious coins. I try to stop the flow; it's too late. He starts yelling, my boss comes out and starts yelling, and I retreat out the back of the store never to return... but not before snatching a handful of silver quarters on my way out.
<bot>: I sliced myself helping a customer, bled all over his stuff and the front counter, and escaped through the back after committing petty larceny.
