Bar etiquette

[paulpablo]

I'm a straight guy. 

I went to the bar today and the bartender wasn't at her station. Another male customer who was seated with a drink looked at me, so I said hi. He said the bartender had just gone out. She (the bartender) returned a little later and I then ordered my usual glass of red wine. The man then asked me if I was from India, so I said yes. He said he was from Punjab (which is also in India). I then went to a corner and had my drink while browsing the internet. After I finished my drink, I went to the till and paid the bill, whereupon the man asked me if I was studying here (Canada). I said yes, I was studying math at the university. He asked me if I wanted to be a teacher, I said I hadn't decided. He asked me if my parents would come to Canada. I said no, they were fine in India. I went back to my corner and continued browsing the internet for a couple of minutes upon which the man started saying something to me. I couldn't hear him, so I went up to him and then he asked me if I wanted more wine. I said I was fine, went to my seat, packed up and left with a weird feeling.

Question: What did I do wrong? Did I break some unspoken rule of bar etiquette?

You need to order a less gay drink and browse sports websites if you're ever in this situation again.

Unless you're from star trek and you just arrived on this planet surely you know that no etiquette was broken.  You just got offered a drink by a man who is most likely gay and declined the offer.
