I haven't used NAG, but I've used products like TLG on occasions where I just met a hottie I saw and liked from a distance and decided to approach and do my thing. Products like TLG are supposedly really good for established relationships, and not for first time approaches (or pick-up as some would call it), at least that's what some members claim TLG to be. And yet here I am hooking the 8-10's right off the bat with a 'mone that's supposed to be a "slow cooker" and not over the head blatant like AV. Why is that? Simply because I wasn't concentrating/looking for the 'mone to do the heavy work for me. I don't have time to get into the details, but if you are following Gladen's side rants when it comes to women, you'll be able to get a good idea as to why it is possible to get them hooked, regardless of which product you're wearing. Pretty much everything he's written about in his side rants, I agree with. He just has a gift to put it all down in words and write all the details and nuances of interacting with the opposite sex.
So, her excuse for declining you when you asked her out "due to her work policy" is just that, an excuse and easy way out for her to save face. It's the same as when they use the "I have a boyfriend" line. They don't want to plain say "no" to you, so a nicer way to shut you down is to come out with one of those excuses. This is from experience from seeing women give those excuses to guys they feel no attraction for, or perhaps felt some attraction in the beginning, but the guy messed it up for himself during the interaction, and then some other guy (usually me...

) ends up getting her contact info, kiss close and in some cases, the "f" close if logistics are right.
I haven't used NAG, but I did test NA oil from a sample Garry sent me. I applied like 4-6 dabs if I remember correctly (this was a bit over a year ago), on both sides of my neck, and yet here I was getting these lovey-dovey bedroom eyes from a few of my cousin's girfriends/wives and some very young hottie friends at a family gathering, when I was just having normal conversation and doing some flirting with them here and there. Quite surprising at the time, because up until then I was under the impression that NA was a "slooowww cooker" from the reports I've read from other members, in which subjects need "multiple exposures" in order for them to get hooked under NA's imprinting spell.
