Interesting post, the section 10 part about not being with someone 10 years younger, that can't be unusual with retired 60+ guys there, how do they get round that?
Last time I tried, everytime I topped up 10/20 baht using SIM company app it extends by a month, can also do at 7 Eleven, also banking app, so do 12x topups etc
Lot's on Lazada to choose from, I blend a Vietnamese one and 100% arabica, works for me. Not expensive either, trial and error, although I keep re-ordering the same ones
