At the airport, there were chaos

ATC (Calls ChamDel7): ChamDel7! Where the heck are you????
ChamDel7: Umm... ACHOO! I have... ACHOO! A cold.
ATC: Don't worry, we hired 3 professional people like you.
3 Days later...
ChamDel7 enters the airport
ATC: ChamDel7, I miss you! Are you feeling better?
ChamDel7: Yes!

Everyone cheers and the hired workers get fired, because they actually didn't do well and suddenly, they hear another plane crash.

The hired workers get fired!
