I'm from NY, Long Island specifically, so when we are there we I go out of my way to not be a "New Yorker". I'm also 6'4" and have been told I can be quite imposing when I want to be. That being said, I know I've given looks to people who I've felt wrongfully cut in front of me, stopped short in front of me, refused to move after I've clearly and politely said "excuse me". I have a rule, I was say "excuse me" no more than three times, after that I will say whatever the next thing that pops into my head, which I will admit at times is not exactly "Disney Friendly", and then throw in a couple of more things as I'm pushing past.
I have never, ever been rude or short with a CM. They, for the most part work long hours in the hot sun and deal with many, many rude people, and of all the times we've been, I've never encountered one that came across as rude or short intentionally. Closest I ever came was March 2014, where my wife asked if there was any chance to change our 1 BR at BWV to a Boardwalk or Garden View. The CM didn't even pause to explain, she just said that we had to call Member Services because it was an upgrade. I wouldn't have thought twice about it if not less than a year prior, the CM at Wilderness Lodge had pretty much FORCED us to take a room with a lake view upon check in. I stopped my wife from pursuing it, and just thanked the CM, after all, it was a room, we were going to sleep there. Not worth it.
I do have one instance where I wasn't rude, just completely engrossed and oblivious...
May 2011. We were at DHS. I went to take a picture of my wife by the Umbrella, and my phone was telling me there was no SD card. This was odd. Being a techie, I decided right then and there I needed to resolve this issue, and needed somewhere to put the phone in order to "operate". Head down, wandering around until I found the closest bathroom, over by where Mike and Sully usually meet. Walk into the bathroom, and begin surgery. After a couple of minutes, I notice that people are staring at me. I didn't understand, nor care, until I noticed that all the people staring at me, were women. Why are there women in the men's room? Then I looked around and realized there were no urinals. Yeah... I was THAT guy.
