Okay -----
1. Meeting in a public place is a given, but try to stay away from areas where there may be children in case you need to draw your weapon;
2. If you are outside, position yourself with the wind at your back with a 360 degree vantage point, and be sure the sun is in THEIR eyes;
3. If they insist on meeting inside, choose a restaurant, arrive first and request to be seated by the door to the kitchen so you have an alternate escape route if necessary; also easy access to improv weaponry should yours fail you;
4. As Stilly said, sit facing all doors and windows;
5. Never sit near the bar. Once the shooting begins, flying glass can put an eye out;
6. Wear jeans for concealed carry in the small of your back; Concealed carry Texas beehive hairdos are a good alternative if you're too bloated to wear jeans that day;
7. Second concealed carry, two words - ankle holster;
8. Tape a Thrower to your left calf if right handed; vice versa if left handed; Should you have sensitive skin that may chafe from the tape, knee socks will work, but are incredibly awkward with heels (some people can pull it off);
9. Be sure and clip an ammo keeper to your bra under each arm for easy reloading;
10. If you are still reading this, have fun
