I did a cold approach yesterday outside gym and later i found myself thinking about how approaching one girl could complicate a cold approach with another girl , if the 2nd girl saw me approach the first one (especially if she clearly saw me get shot down by the 1st girl).

With this problem in mind, how do you guys do 8 cold approaches an hour at some mall? Do you switch your location frequently within the mall, so the other girls you approach couldn't have seen your first approach?
