Harassment at Mcdonalds

I broke down today and joined the Mcdonalds craze that seems to have a hold of this city.  The lineups to the registers inside as well as the outdoor walk-up window remind me of Tim Horton's back home.  In a desperate move for food at a late hour before starting the overnight shift at work I hit the walk-up window and placed my order with the fewest required words possible. 

After a few practice runs in my head of what I needed to say to order what I wanted I was ready and as long as the McEmployee listened to me there wouldn't be a problem.  Today, however, I got the guy who felt like throwing some questions into the middle of my practiced order.  He completely caught me offguard and I lost my focus so after taking a  moment to come up with a response to a question i didn't understand I gave up and told him I don't speak Russian. 

He knew a bit of english and his translation of the question turned out be 'boy or girl?' I started thinking.....

1)  I thought my gender was obvious enough
2) When did asking your gender become part of the ordering process?

I felt emasculated but refused to answer his question and simply repeated my order in a deeper voice.  That seemed to work. 

I realized later that maybe he thought I ordered a kids happy meal or something where the toy that comes with it is gender specific.  This makes the most sense to me but still not sure how he would hear me order that as the Russian pronunciation of Big Mac is ..wait for it....Big Mac.
