I have seen 2 youngish farang fighting over a boy, even as recently as the main Songkran day on April 19 in Jomtien complex
It wasn't so much a fight as a tug-o-war, and i don't think the boy was actually interested in either, he was just loved-up songkran style and having too good a time with friends!
Back in my early days visiting Pattaya i recall being in Le Cafe Royale late at night with my boy of the day and a boorish farang came up to our table and offered to pay my boy double whatever I was paying! Thankfully I was 40 years younger than the boor at that time, so the boy chose to stay with me!
