Note: This is a true story.
You're checking into a 4-star hotel.
There is a long line, and several people are in front of you.
The girl at the front desk is apologizing because apparently a group of about 60 soldiers checked in unexpectedly and she's having to re-arrange the accommodations.
She checks a lady into the hotel and sends her to her room. Lady seems glad to be out of the line and makes her way toward her room.
The desk girl starts checking in the man in front of you. The process takes a while. You begin to tap your foot impatiently.
A few minutes later, the lady who was checked in comes back to the desk. She doesn't look as happy as she was when she left. "Miss," she hisses through clenched teeth, "there's a problem with the room?"
"A problem?" the desk girl cries, "What seems to be the problem?"
"Miss, I used my key to get into the room you gave me, and... there was a troop of soldiers in there. Let's just say that after a long day they had apparently been excited to get out of their uniforms and make themselves comfortable."
The flustered desk girl tried to make amends, but you don't remember what they were because you were trying very hard to conceal the laughter brought on by this entertaining occurrence.
