I've seen people sip water for more than a quick second so it isn't out of the norm. I don't know how long they sipped because that would look weird of me but it wasn't quick. I just tried seeing what it would look like to sip out of something like N02 but bigger and it doesn't look weird especially with the straw. As far as using the MFLB in public where you can easily be seen I would definitely look at someone who is cuffing their hand and put it to their mouth because the first thing I'm thinking is that they're either about to spit out a razor or spit out some rocks(cracks) or they're putting the rocks into their mouth. Either way I'm watching and gonna put extra attention to that person and if I'm doing this you know someone who does it for a living is watching closely. All they have to do is make up a fake reason to stop and frisk you. If they find herb on you, you have a possession charge, a paraphernalia charge, and a smoking in public charge. All because you brought unwanted attention to yourself by putting your hands to your mouth too many times in a place where it wasn't warranted like on a train on a warm or hot day. No reason to warm your hands. If your in NYC you know how many plain clothes undercovers are on the trains and in the parks or in yellow cabs so you never know who is watching. The only time I would use anything on the train is when there aren't many people on their and late at night when the po po get relaxed, other than that no way. I think people forget herb is illegal and even though we see no problem with it a lot of people do. Even those who don't see a problem with it need to fill quotas and making yourself seen makes it easier for them to help you catch a case. Remember a lot of cases are started because of people being caught with herb usually from them doing it carelessly and bringing attention to themselves and they get caught and a lot of times that small charge leads to bigger charges. Why go through all of that when you can lay low while still enjoy yourself. Most of the time cops don't know what to look for anyway. If you look at most of the people who get caught it's because they are just plain simple in the way they do things not because the cop was extraordinary with their senses but they are good at knowing what to look for if they are used to it and if your from a big city they know because most people do the same type of tricks and they are good for seeing what is out of the norm but most people do that also, cops just use that as an excuse to question you or watch you thinking that they are Matlock.
