... Never before have I encountered such arrogant rude people in my life...
And now a short list of other places Liberty DickFlap has never been, seeing as how he has never encountered such arrogant rude people:
French restaurants
New York
Sporting events
Bars
Automobile dealerships
High school
Australia
crowded subways
banks, credit unions, investment brokers
We probably shouldn't tell him about 4chan, SA, and all the rest of the internet.
