Having worked on my sun tan a little (I have been informed to only return home with a good-colored skin), I spent an hour or so at the swimming pool, and then I took a cab to the Gambler's Book Shop at 630 South 11th Street, Downtown Las Vegas. After the taxi driver refused to wait a little for me to return from the book store so he could take me back, yes not even against a significant extra fee that I offered to pay him, he seemed very surprised that as a result, I was unwilling to give him a huge tip. I actually liked my own line: "So, you want me to tip you big for not wanting to do me a favor?", but the guy behind the wheel did not see the humor of my remark. After a big semi-bluff on his part, where he locked all doors and threatened to call the police if I didn't give him any extra, I called his bluff by saying that I actually wanted the police to come - so I could tell them what a scumbag of a taxi driver he was. After some fuming on his part, I turned out to have the best hand - my opponent folding his bluff face down.
