Hello, I am currently stuck in the Dallas airport for who knows how long. I don't have a car, am too young to rent one, don't know anyone here and don't have enough money for a hotel room so I am simply stuck here until I can get on a flight, and I'm flying standby so who knows how long that will be.

I didn't expect this and have now used up all my zyns. I saw that they sold velos at a couple of the duty free shops so I went to purchase but the lady (incredibly rudely and loudly) told me I couldn't buy it because I wasn't flying internationally (I didn't know this). I wasn't upset by this or anything, rules are rules, but a bit taken aback that she yelled at me and then waved towards the door when I asked a very polite question. But I suppose that's besides the point.

Anyway I'm just wondering if there's anywhere else in the airport, not duty free, that I could buy some sort of pouches, or even nicotine gum, anything that isn't a cigarette or cigar. I really, really do not want to start having withdrawal symptoms when I'm already extremely stressed and will most likely have to sleep on the floor of the airport tonight. My withdrawal symptoms are incredibly bad and I'm pretty worried right now. It sucks to be dependent on this stuff.

Thank you in advance
