New here, browsing these very interesting TJ threads. Live in SD so have had my share of TJ experiences, mostly at AB. Haven't been in about three years, so doing some recon work here to see if there are any better spots than AB.
Regarding the guapo discount, doesnt suprise me that a Mex or MexAmerican guy is more likely to get freebies as they represent viable boyfriend potential. I am sure any of the chicas have been warned repeatedly about falling for the traps and lures of a gringo who promises to "save" them. Some gringos might break thru that layer of innate distrust, but probably takes some work.
Personally I monger so I dont have to do any work! I've been molested at AB many times by chicas saying oh you are so guapo (no I'm not Brad Pitt but rank as good looking), but find it a total turnoff and try to make it clear I want to be left alone. Dont know if being harassed and molested means I would get a freebie, but I wouldnt take it anyways. First, I monger to be in total control of who and what I want. Second, somewhat decent guy that I am, paying for it voids any regret, emotion, responsibility. Of course, if I am into it and on my best behavior I am accustomed to getting "extras" but that's a different deal altogether.
That's just my psychology and cuz this view hasnt been expressed yet on this thread figured it was worth posting.
