Well if you're going to be gaming at the malls do it in the individual stores and not in the thoroughfares/walkways where people are in transit. Women walk quickly when going between stores but slow down their pace when they are browsing/shopping in a store. Use this to your advantage. Women also know that guys use the walkways as "scouting" spots when they want to pickup women. We've all seen it: a group of guys hanging out at a busy spot of the mall just looking at all the women that pass by, laughing and jeering each other on just to talk to one of them. When they do it's usually something crude, stupid and they end up crashing and burning. You don't want to even be associated with any of them, so don't approach like them. Besides, approaching in a store just seems a lot more innocent. Two customers having a conversation is better than a guy trying to catch up to a woman he doesn't know to talk to her.
I'm an avid reader and have found excellent success in book stores at the mall just starting up conversations about reading material. Clothing stores are another great place by simply opening up with a simple "what do you think of this?" "Does it look too _______?" Use the surroundings of the store to your advantage to find conversation material.
Malls are one of the best place to hone your skills as a PUA. The only problem is, every single other guy and his best friend also try to use the mall as their gaming spot, so you need to be on it.
