I saw a very funny sight at L section 2 years ago. The numbers stopped being called out and a bus load of people who looked like Chinese entered the L section with just passport and an application form as far as I could see, and left within minutes with a receipt in their hands. TR section extension where that is just feasible is 'round the corner.Things subsequently tightened up with long standing agents having problems so perhaps things got a bit much.
It seems work regulations are being waived in the 'Lower Sukhumvit Free Trade Zone', although I suppose the 4 Thais per foreigner are back in a Lawyers office, but I am surprised waiters are paid the minimum Bt40,000 salary required which I thought was required with a few exceptions. Whether ASEAN is also an exception I don't know, but Bangladesh seems not to be listed as a member.
