Crazy People are Making it very Hard for me to be Nice

Josh and I endured what can only be described as an awkward and creepy encounter with another patron at Royal Mile whilst having dinner on Friday night. Here is a rundown of what transpired, told from my point of view:

(Man sits down next to me at bar, looks at me and does a double take)

1. Yes, I am Filipino. Thank you for noticing.
2. Oh, that is mildly interesting that you're familiar with Filipino women because you were stationed in Manila during the Vietnam War.
3. So you're saying Barack Obama isn't a military man, and that's the root of the problem, huh? FYI-I don't care to discuss politics...ever. So you should go ahead and be on your way.
4. Yes, I think you mentioned that you were a Vietnam Vet.
5. Now, I'm turning away from you, staring at my food and giving very non-committal responses. This is called non-verbal communication and in many social circles signals the end of this conversation. You should leave me and my husband alone to enjoy our fish and chips (sans chips).
6. That's right, you should listen to the bartender who just asked you to stop talking to us and leave.
7. Oh, wow. You're a Vietnam Vet! That is brand new information, buddy.
8. Yep, got it. You were in Vietnam.
9. The fact that you were in Vietnam years and years ago hasn't changed in the past two minutes. But again, thank you for clarifying and telling me for the umpteenth time.
10. Okay, that's enough talk about how hot Filipino women are and the elbowing gestures are too much for me--this is creepy. Maybe you should go back to talking about Vietnam.
11. It's official...I'm angry at you for these reasons: 1) I have been working very hard to not wear a bitchface to the bar and this is certainly making me take steps backward in my progress and 2) Because it is very clear that you will not be leaving me alone, I am forced to eat my dinner as fast as possible so as to make an escape. So fast that I don't even get to put malt vinegar on my fish! This is bad.
12. Good job, Joshie, getting the bill and paying ASAP.
13. Run, Josh, run! Let's get the hell out of here!
