Be a mullet
Unless you're being extemely careful, your days are probably numbered. But it's possible to have your cake and eat it too. I've played in a couple of local casinos for nearly a decade now using a valid comp card. To do so, you just have to be the perfect gambling mullet. A few suggestions:
Always "filch" chips to skew the numbers southward. Stay consistent with the amount. And don't get too greedy. At only a chip every other shoe, you'd be surprised at how much losing that equates to in the casino's eyes over the long haul.
Nurture relationships with casino personel. I can't even tell you how many times a friendly pit boss has asked me for verification on my buy-in. If there have been several rebuys, I always inflate the numbers. I've even asked them to fudge on my account a little to help me make up for "all these damn dealer blackjacks." That request always gets a chuckle and sometimes results. I've also learned a great deal about casino operations, shifts, and people to watch out for.
Make sure that your counting is almost subconscious. Use numbers in your conversations with the pit boss. Talk about that dealer seven card 21 that drilled you or about the ages of your children or what you paid for that steak dinner at the other casino. (In cse you're wondering, I use one of those obscenely easy unbalanced counts. No matter what the distraction, if I can see the cards, I can keep the count.)
Vary the time of your playing sessions and shifts. Gamblers sit at the table for hours when they have time. Gamblers stand and play for ten minutes when they're "meeting some friends" or are "headed to the craps table" or are "waiting for that cocktail." Gamblers don't play particular shifts; they play when life allows them to get to the casino.
I know all this may seem a little over the top, but 75% of my play is at casinos where I'm known by my first name. The dealers and pit personel like me, I couldn't possibly be counting cards while I'm visiting with them, and casino records show me to be a loyal patron with substantial lifetime losses. Like, I said, the perfect gambling mullet.
Hope some of this helps. Best...
