Learning to Lie

I was taken to a place where they had karaoke.
They served drinks of many kinds, and lovely fruit.
There I was taught to lie. Using two sets of what you see below. (Does anyone know this game?)
I do not lie. It's the truth.

I learned to lie so well that I won many times.

It helped that my opponent, who was also my teacher, had to drink lots of alcohol each time he lost. His judgment became increasingly impaired.

I, on the other hand, drank water when I lost. I discovered that the toilets in this place is nicer than a 5-star hotel. I wonder if it is because the patrons spend a lot of time there.

But would they notice if they did?
