Consider "Social Wonging"
I've gone to Vegas with non-counting friends a number of times. Sometimes they know I count and sometimes they don't.
To someone who isn't that much into gambling, nothing is more boring than being stuck at a casino waiting a long time for someone else who is in to gambling (or counting) to "get their fill".
So, my solution is a compromise I call "Social Wonging".
Often the people I go to Vegas with are not as familiar with it as we jaded counters are! They want to "Ooh" and "Aah" over the new casinos, the oppulence and/or the tackiness. I use this to everyone's advantage.
If my companions know I count, then I tell them (in advance) that if I see a table that goes positive, I will stop and play a few hands, and it will likely only last a very short time, so they should either walk on ahead look for a slot machine or something else to amuse themselves briefly. As soon as the count goes bad, I will get up and we can all continue on with our little "sight seeing" tour.
If they don't know I count, I just tell them (in advance) that I am good about being able to tell which tables are "lucky" and I pay hunches, and may sit down to play for just a few hands whenever we are walking, and again, as soon as I get up, we can all continue the tour of properties.
We all stroll down the strip, going in on end of a casino, out the other end and right into the next casino. All the while, I am watching for tables to wong, and jumping in when I see them. Often, it is myself, another couple and a lady friend. Frankly, walking with a group of obvious ploppies is pretty good cover. (After all, how many self respecting serious counters are going to be strolling through a casino in a group?) I just sit down, play the plopy role, and then get up and (still playing the ploppy role) move on with my group.
Since these folks really are all ploppies, they genuinely exude that "Wow!" attitude when their friend "gets lucky" and wins a few hands. That is pretty good for cover. From the PB's perspective:
A guy is walking by with what appears to be his wife and another couple. On "impulse", he sits down at a BJ table, and wins a few hands, while the rest of his group either watches him (no counter would ever want people standing behind him and watching him, would they ?) or they find the nearest slot machine or check the rest of the place out. After a few wins, he, being of modest midwestern sensibilities, decides to quit "while he's ahead", or "before his luck runs out" or "need to catch up with his group" ( A.K.A. the count just went bad!) and he rejoins his group as they sight-see on. Pit bosses see the "for real" version of that scenario many times every single day in Vegas.
Also: You know how the showrooms always make you show up early to pick up your tix for a show, hoping you'll spend a little time in their casino while waiting for the showroom doors to open?
Don't disappoint them! Do a little Social Wonging, while your friends check out the joint and sight see. Then rejoin them when the count goes South and you can all head to the showroom together. I absolutley love doing this, since I get to see a (usually) good show, enjoy being with some friends and often make a little money to boot.
If I want to put in some serious table time, I do it at some point when we are all apart doing our own thing, or I just get up extra early in the AM and play then. In the latter case we all just agree to meet somewhere at a given time.
Yes I give up some EV by Social Wonging, as opposed to serious lone play, but its a great way to ensure that everyone has a good time and you get in some BJ time as well.
Hope this helps,
