My first time in Vegas

I stayed for one night. Checked out in the morning, the bill was $250, and they had added resort fees, and I asked what the heck is that for?! She said the hotel had a pool and internet here and available for use. I said I didnt even use them! She said “Well they were here and available and you could’ve used them.”
So I just wrote out a check, but made it out for $50 and handed it to her. She said: “Sir this check is for only $50.”
I said “That’s right! I charged you $200 for sleeping with me.”
“But I didn’t!” she said.
I said: “Well I was here and available, and you could have!”
