SWING (Service Workers in Group) Foundation is an NGO that is very active in the Pattaya area in giving out condoms and sexual health advice around the bars, clubs, massages shops, karaoke's etc. Quite similar in nature to the "Take Care" group that used to be around a few years back
They can often be seen out and about in their colourful t-shirts https://www.facebook.com/PATTAYA.SWING/
Unlike a lot of NGOs this one does not appear to be staffed by interfering FWCs (Fat White Cows) and instead is staffed by local Thais, who are interested in helping the health of the Pattaya Sex workers
