I searched PETA's website to track down the original letter they reportedly sent to Hun Sen. I could not find it. I was keyed up about it, because one of the news reports which I read (which I also am now unable to find) quoted their letter as saying something to the effect of,
"Foreigners do not come to Cambodia to eat KFC,"
suggesting that a KFC invasion will spoil some tourist's Authentic Khmer Experience. Moreover, I am pretty confident that the people in power do not care where I eat.
Visit any of the growing number of fast food restaurants in Phnom Penh and you will immediately note that nearly all their customers are Khmer. And the times I have visited, they are packed!
