Shorty & Curly

I often work by myself, and have learned to be actively aware of thieves, be aware of my personal safety, and hold in pee for uncomfortable lengths of time while desperately clutching my groin and dancing on one foot.  This story involves the first thing.
I was talking to my friend Jule at the counter about all of the rude, uncomfortable, and generally bizarre behaviour some of my customers exhibit.  We were exchanging retail-based horror stories when two men wandered in, one short and one tall with curly hair, like Daniel Stern and Joe Peski in Home Alone.
Curly had been banned from the shop years before, after attempting to sell stolen CDs. I knew who he was, but decided to merely keep an eye on him and only approach him if he displayed any suspicious behavior.  I've learned to pick my battles.
I told my friend about how he had stolen CDs from the 4ZZZ library (Brisbane's premier community FM radio station) including an album by one of my workmates; and then tried to sell that very batch of CDs to said workmate.
We laughed over the sheer buffoonery of that situation, when suddenly the security doors went off, emitting a shrill beep.
''Scuse me,' I said, and walked briskly to the doorway.  It was Shorty, and and he was out of the shop doorway by the time I got there, so I ran onto the street, yelling 'excuse me, come back here please.' He pretended not to hear me for a while, but eventually came to a stop.
'I'm sorry, but you set off the security alarm when you left the shop, so I just have to have a look in your bag.'
He handed me his back pack, and as he did so, I noticed that he had four or five DVDs tucked conspicuously under his arm. With our price stickers attached.  And security tags inside.
'Those are our DVDs,' I said.
He handed them to me, saying, 'The doors beeped for no reason.'
'Um, no, they beeped because you just stole DVDs from me.  Which you just handed to me. Just this minute.'
He pulled the whole 'I didn't know I had them' line, but didn't put up much of a fight.  He even walked amiably with me back to the shop, where Curly was waiting.
'I'm going to have to look through your bag too,' I said.
He obliged, though not so willingly as Shorty.
'Look guys, I'm not going to call the police, but I'm going to have to ask that you not come back here.  We've dealt with *you* before (I directed this at Curly) and you know full well that you're not allowed in here.'
He said that he didn't know what Shorty had been up to, and I replied that regardless, he had a prior history.
The DVD thief left, and I waited for Curly to leave.
'Hey, are you selling tickets to the Misfits?' he asked.
'No, now I'm sorry but you need to leave.'
'Okay. How much is this poster?'
I blinked and said, 'I am actually not going to interact with you.  You need to leave. Now.'
He wandered out, unfazed, and I returned to the counter, where Jule was waiting for me.
'So, what were we talking about?'
