Not only the Thais roll up their trousers and wade, I got caught out eating at a local food court when a rain storm struck. Three feet of water to wade through to get home. The trucks going past almost swamped me. Then I reached out to a post to support me while I stepped off a kerb into the unknown, not knowing the post was full of huge cockroaches that had climbed up out of the water. Whatever , I kept holding and stepped off into a dip that had me up to the waist in water. Life is always exciting in Bangkok.
