I noticed a really great way to clear a few excess players off the table in the last few days! Simply cough a bit and casually announce,"Gee, ever since I got back from CanCun the other day I just haven't been able to shake this cough!"
There are many other legitimate ways to trim down the table when you want to.
Just double down with 12 against a 2 for 1/10th of your bet.
When you have 16 vs. 10, ask your neighbor,
"Did I hit this last time or stay? I always try to alternate with my 16's".
Take Insurance on your next stiff for 1/10th of your bet, remarking,
"Of course! You gotta Insure a 13."
Double down with 16 vs. 7 for a ridiculously small sum, then tip the dealer the extra part if you win the hand.
When you've got 20 vs. a 4, 5 or 6, pause, and feign splitting before "coming to your senses". If you've read your neighbor for a "sacred flow" type player, ask if he wants to go partners on the split. Although he actually should, he'll be too terrified of corrupting the shoe. Then you can back off.
Keep going back and forth from playing one box -- to two boxes -- to one box.
Double A/8 against a 5 or 6, even at a neutral count.
Be sure to split 2/2, 3/3 and 7/7 vs. 8.
Be animated so as to appear financially suicidal.
Anybody who can sit there through all of these is probably crazier than you look.
