A repeat from April 2016, but relevant here...
Back when I had to man the front desk, students knew that jumping the queue was a Very Bad Idea.
One guy didn't, and he barged past ten other students queueing up patiently in front of him. Strike One.
He then started talking down at me like I was stupid. Strike Two.
That didn't get him what he wanted, so he started screaming insults at me. Strike Three, you're out !
"Right then, let's see why your account is suspended..."
<clicky clicky clicky> DING DING DING WE HAVE A WINNER !
He was still screaming abuse at this point, so I decided it was time to shut this loon up. I raised my voice from "Normal" to "Everyone In The Building Will Hear Me"...
"YOU ARE MASSIVELY OVER QUOTA AND YOUR ACCOUNT IS FULL OF JPG FILES WITH PORN-RELATED NAMES LIKE DOG-SCREWS-MILF-001.JPG. QUITE A CATALOGUE OF IT YOU'VE GOT THERE, SON !"
Did I mention that all of the other students in the queue were female ? If looks could kill, he wouldn't just be dead, he would have been a rapidly expanding cloud of greasy particles.
Chummy suddenly lost his composure, and I suspected that bladder/bowel control were about to go too, so I let him beat a hasty retreat - hey, I didn't want him soiling the carpets !
"Next please !"
