I go for an early morning 90 minutes walk every day, The footpaths are a total disgrace, the quality of proper paving is totally ignored. Just take a look at the quality of paving outside of the recently constructed high rise resort hotels, Just prior to completing constructing the resort they get their workers to rip out all the old pavers and replace them with larger square pavers and install them properly. It's definitely obvious that the more qualified workers do the job properly. Another thing being married to a Thai lady for 22 years I soon learnt that Thais have a short cut for everything, even if it's unsafe they will go for it. Hence the deaths and serious injuries in Thailand.
