Short answer: Yes.
Long answer: You're a grown ass man wondering if you should get a sandwich because you're hungry. What the fuck is wrong with you? YES. Get your damn sandwich. Nobody can stop you, man. If they do try to, fuck them. If there's not a Walmart near you, then you're screwed, and I do feel bad for you then. Otherwise, get the damn sandwich. I sure as Hell would. Then again, I'm me. If I'm craving bacon, you can bet your ass I'm getting that shit. As long as my bill are paid, if I have some extra cash to spend on me, I'm fucking doing that shit.
