Woman checking out.
FD: "$$$ for the room, $$ for Dinner room, and $$$$ for the 20 minutes long distance phone call."

Guest: "LONG DISTANCE PHONECALL?"

FD: "Yes ma'am. On my record, you've made a 20 minutes long distance phone call last night to this number, ###-###-####"

Guest: "I don't recognize that number sorry."

FD: "...That's what it is said on the record. Is ### your room number?"

Guest: "YES BUT I DIDN'T PHONE ANYONE."

FD: "...But it's......."

Then they argued for about 5 minutes,

FD: "Fuck! Have a nice day."
