Night off

Standing in the back of a club, after the bars had finally shut, I'm watching the last desperate attempts to pull from the foolish and unsuccessful.
I have to stand blocking off a doorway to a room that was by that time in the night closed to punters. A lady who has otherwise failed to find a new warm bed for the night approaches me. She's 22-26 years old, brunette, reasonably dressed, reasonably attractive, relatively sober. This rings alarm bells. At this time of the night it's only the inebriated and the odd left.
Nubile, attractive and coherent immediately rings alarm bells.
"So when do you get done?"
"Not 'til the last ones gone home, I've had a drink and a burger, then a long walk home"
"Oh, that's a pity, when's your night off?"
That's an unusual strategy, most of the business is about immediate gratification, most punters don't think past the next drink, the next dance, the next pull. The idea of a strategy that extends beyond the next couple of days is beyond most of the clientele.
"Sorry love, I'm not off 'til Thursday, then I've got some drinking, sleeping and quality TV time to catch up on."
"Oh well that is a real pity. I was hoping you'd take me out and show me the town."
I'm still very sober, very cynical and quite tired.
"Well love, you've made it to 3 in the morning in this town's premium venue, there's little of this town left for you to see and none of that I'd want to drink in. You'll not be seeing me on Thursday."
"Pity, Oh well."
At which juncture, she heads straight out the main door and heads off into the night. I don't need a flag waving to tell me she was flirting, I also don't need a banner waved to tell me that she was serious. I was tired, sober and I don't bring my work home, or onto my night off. There's only one night off a week and I will spend my time drinking with friends, not baby-sitting a nut job while maintaining my night the wrong side of sober for my sole night off.
