11.45 am: Hi, welcome to GoNowhere Airlines, can I see your id and flight reservation details?

Yes, here they are.

Clatter, clatter, keyboard clatter

Oh..

Is there a problem?

Well YES, you're already checked in. You checked in at 6.30am today.

NO I didn't. I'm here NOW and I'm checking in now.

But you've already checked in.

NO, I definitely haven't. I'm here NOW, with my id, my receipt, my baggage...

But you checked in at 6.30am this morning.

NO, I definitely didn't.

Oh....

Ugly scowl. Supervisor called. Clatter, clatter, keyboard clatter.

Supervisor : You already checked in at 6.30am this morning.

NO, I definitely haven't. I'm here NOW, with my id, my receipt, my baggage...

The system has you confirmed. You already checked in at 6.30am this morning.

NO, I definitely didn't. I just arrived ten minutes ago.

You must have checked in on-line.

NO, I definitely didn't. Why would I do that when I have baggage for the hold?

The system has you confirmed. You already checked in at 6.30am this morning.

At 6.30 am I was still asleep. I definitely haven't checked in. I'm here NOW, with my id, my receipt, my baggage...

Oh....

Menacing wince. Manager called. Clatter, clatter, keyboard clatter

Manager: You're already checked in. Step aside.

NO, I'm definitely NOT. I'm here NOW, with my id, my receipt, my baggage... Someone MUST have made a mistake and checked someone else in as me. I'm me. I'm NOT checked in. I'm here NOW, with my id, my receipt, my baggage. Deal with it!

There's no need to take that tone.

Clatter, clatter, keyboard clatter.

12.30 pm This check-in's closed. You're grounded. Have a nice day!
