I took my kids to Legoland in Windsor a couple weeks ago. My son said something about the water on a water ride, but he pronounced it the American way with a "d" in place of the "t" (as in Wa-der). A nearby girl spouted out in her cockney accent, "Did you hear how he pronounced the word wa'er?"

Many Brits tend to eliminate the t's in certain words. I've also noticed a lot of vowels added to the ends of words ending in vowels (Angeler instead of Angela, Christiner instead of Christina).
