Forgot to post this, but it happened to me yesterday during the day. I opened the bar up at work at 10.30am, 2 guys in their 30s walked in at about 12ish and bought a couple of beers and went outside to the terrace. One guy lit up a cigarette, even though there are no smoking signs on the tables and one BIG sign right next to the table they were sitting on.
Me: Excuse me sir, I'm afraid you're not allowed to smoke. You have to-
Guy smoking looks at me, interrupts me by blowing smoke straight into my face.
Smoking dude: What are you going to do about it?
I stare dead straight at him.
Me: Get the fuck out of my bar.
He looked a little taken a back, but takes another drag and blows more smoke in my face.
Smoking dude: Really? Or else what?
Me: Get the fuck out of my bar, or I'll get the duty manager of the hotel to kick you out of the hotel.
He ignored me for about 5 seconds, me standing there.
Other guy: Hey let's go.
Smoking dude grumbles a little bit, finishes his beer. They get up and leave.
Me: That's right, fuck off and don't come back asshole.
I hate pricks like this. I'd be fired 10 times over for swearing at the shithead though.
