ho ho ho. How low can you go? I will tell you, all the way down to the bottom. That is where your miseducation got you, the bottom of the sea. Like a sea urchin or sea cucumber. Plant or animal? I think labelling you as a plant is disrespectful to our plant life. Best compare you to a puddle of stale water, breeding pests. You are in fact the very definition of a pest.
I too am British (not proud of it) and have had many visa exemption stamps on arrival. I was told by Trang immigration that the best way for me to make my retirement visa was to convert it from a tourist visa when within Thsiland. There are also many other reasons why prople may opt for a tourist visa rather than a visa exemption stamp. But I won't spoil your fun by explaining it all to you when you can busy yourself by conducting your own fact finding. Originally I was applying for a retirement visa but because Bangkok Bank will not issue a statement to anyone who is outside Thailand who has not previously added their account with the 800,000 baht in to the bank's app I am returning on a tourist visa. The advice being that they can be reluctant to repeatedly give exemption stamps too many times in a 12 month period. Common knowledge apparently.
