If we win a decent jackpot we blow it on a nice dinner. It's all about having a good time, we don't expect any life-changing wins. The most we ever won was $2,700 on a QuickHit machine.
The only game I will play solo is blackjack and it's only the 3:2 tables and basic strategy. My wife finds that game boring so I'll go to the tables when she's at the pool or something. If you play disciplined basic strategy, you should last on the table for hours but if I get lucky in the beginning and go up a hundred dollars or so, I'll cash out. Otherwise, I consider breaking even after a couple hours of play a victory. That includes tipping the dealer.
One time back in the late 90s we were at a casino in Carson City. It was still using the coins - hadn’t yet upgraded to the paper. She put in a quarter on the first pull and got the jackpot. The quarters kept falling down. I laughingly asked her “How did you DO that?” She laughed back “I don’t know!”
We took the winnings and left for a nice dinner.
