I can't afford your game, man

I went to the car wash yesterday, and the guy hooked me up with a $22
wash for $13. I said thanks, and tipped the fella $2.
He notices one of my poker books on the seat, "So, you learning the
game?"
Sly smile, "Yeah, a little bit."
"Well, when you're ready to step up, I can show you a game downtown."
"Yeah?" I'm always happy to know of another game.
"Yeah, the guys play big time!"
Cool! "Really, what's the limit?"
"Well, the buy in is $20..."
...
...
"So, cleaning the rims is included in the price, right?"

... in the likely case that I take everyone's $ there, I still have to
pay for gas to get there.
