Und get off ov my lawn.
They weirded out the bitchy customer enough to make her shut up and leave. That’s a win in my book!
I always thought “pawned” should legitimately be an intensification of “pwned”; “pwned” to an extreme degree.
The hierarchy would be:
“owned”: I took possession of the subject.
“pwned”: I really mercilessly seized the subject against active resistance.
“pawned”: I crushed the subject’s resistance, ruthlessly and absolutely captured the subject, and then sold it off cheaply in order to demonstrate my disdain and low regard for it.
ETA: I see that Tahssa above has the same idea.
Think about it this way.
A bitchy, irrational, borderline-psycho customer abusing the system and the staff in a checkout line is wrong. A pair of random weirdos* singing a paean to an ancient god of death and horror at the top of their lungs is wrong.
While two wrongs cannot make a right, sometimes they make a hilarious. That, and the fact that douchebag customer fled the field of combat, is how and why the “lady” was “pawned”. (See previous post about the intensity hierarchy of “owned” and you’ll see that “pawned” is, in fact, appropriate.)
*No offense intended, flatlined. Both the described act itself and the mere fact of active SDMB membership are pretty clear evidence of this on your part.
I don’t find anything about what you guys did to the lady funny at all.
Because the song was lame, or because the woman wasn’t deserving? I don’t think the song was “funny” per se, but it’s pretty funny that she got annoyed after being clueless at best or entitled at worst about how coupons work.
In other words, just like Chthulhu?
I must listen to that song until I have the words memorized.
2nded. Worked in retail a lot and nave little patience for entitled angry customers who think they should be able to change policy to suit themselves, or that just bitching loudly is a sure fire way to get what you want.
It’s nice for the employees who are instructed to be restrained when other customers take over. Quite the unique manner as well. 
The beauty of it is , rather than address the lady directly and tell her she’s being an unreasonable pain in the ass, they just start singing something really bizarre. She obviously knows it’s her bad behavior that prompted it, regardless of lyrics.
I think the could have sung just about anything. The Beatles “All you Need is love” or anything and she would have been pissed but his choice was not only bizarre but cool because of the other person joining in. I wish I’d been there.
You pull the crap that lady did all the time don’t you? Where do you shop? I’ll start shopping there in hopes a live demo will clarify it for you. 
When I had a very similar episode, I loudly asked the cashier how late they were open (I was next in line with 5 more behind me). She told me 11 pm. It was currently 5 pm. My follow up question, “Think I’ll make it?” raised laughs from those behind me.
I think she probably knew she was behaving badly and knew the bizarre song was for her sake.
Imagine some irate privileged customer , knowing she was holding up the line, and people just start singing and smiling at her.
She knows the real message is “you’re being an ass”
LOL!! was it in any way effective?
Customer remained clueless. Everyone else had a laugh, cashier included.
Well I had a laugh as well. Thanks.
I used to instruct my cashiers to not let customers engage them in lengthy questions when people are waiting in line to check out. The cash register is for paying ,and the other staff is for questions, but you can’t avoid it all the time.
Actually, pawned implies that he received a loan using the lady as collateral.
pwned
Are people taking you literally, Flatlined? <snicker, snort>
Never heard of the song. I was hoping you’d Rickrolled her.
I wish I’d been there.
