a) apart from huge, mostly broken, screens along the beach one still has to find public toilets available to anyone along the beach
b) I've seen hundreds of Thais, mostly drivers, peeing along wherever they stopped to poles, walls and if someone wants more detailed studies, visit the food stalls along lower Sukhumvit after 11pm. Most Soi going off Sukhumvit smell of urine as none of those food vendors offer toilets
c) while the stench is less than pleasant it is noteworthy, that if this is the only liquid "pollution" being released in public, then Thailand might just have become the cleanest country on the planet.
Stop this bashing of non-Thais, if your own people do the same or even worse. Stop splurging money into absolute nonsense as long as there might be the possibility to erect 50 - 100 toilets along the beach in Pattaya, Jomtien as well as all other beaches facing the Gulf of Thailand.
