When we were in Australia at Worlds back in 2006, at a restaurant, I was absent mindedly reading the menu as our waiter was standing near us. I pronounced beer as "beee-yah" without realizing it. The waiter noticed it, however, and just walked away. Another waiter ended up serving us. I'm fairly sure I picked up that pronunciation from the Fosters commercials ("Australian for Beer").
Unsurprisingly, I named the beer t-shirt "Beeyah"
Yay! My design streak is alive!
