Not so fast, jonnieb: these alcohol rules were already in existence, and are aimed at 7/11s, mom & pop stores etc. There will be no change to entertainment venues. Whether or not enforcement is carried out against the 7/11s etc, remains to be seen. Given Thailand's record to date: i doubt it.
For as long as anyone can remember Thais have flouted any law deemed "inconvenient" to them, often paying bribes or "tea money" for an obstacle or problem to "go away".
"Uncle" Prayuth and the NCPO are trying their best to change the thai mindset, to being more law abiding citizens and cleansing the corruption. It'll take decades, of course, and will probably fail, but at least they're trying.
And for your information: I am now paying the least amount of "tea money" per month than at any time of my 8 year tenure at C & Ds ! By a wide margin!
I don't like everything Uncle Prayuth's doing, and i'm sure he's also ensuring the elite continue to prosper, but so far i'm far more impressed with him than the previous so-called governments, who were just a bunch of self-interested clowns, making Thailand look ridiculous.
