I did one there in September, same, 30 minutes in and out all done. I got there at 8.30 am. I think the reason why it isn't as busy as it use to be is the visa exempt 60 day stamp. You don't have the old 30 day extension people queuing up to extend their short visits. The 60 day Visa exempt is pretty darn good for everybody including the immigration officers.
I went to a well known company in Thailand 14 years ago. Firstly there was no real eye check with proper machinery and a microscopic look at my eyes. They sat me in a chair and kept giving me glasses to try on until I got a pair where I could see clearly. I got 2 pairs of glasses for 9,000 baht. In Australia totally different. Went to Specsavers and had a free eye examination where they had all the gear to check your eyes properly, no guessing. I could have got 2 good pairs of glasses for 4,400 baht but opted for a better style with anti glare, that came to 6,600 baht (equivalent to AUD). The Australian service by proper medical professionals and 2 pairs of glasses included was far better and cheaper than Thailand.
I don't, I keep my money in Australia where I am receiving 5.5% interest from ING bank. The point I was making is that the Thai savings accounts pay around .75% interest and then they deduct 15% tax off those earnings. It is way more beneficial to keep your savings in your home country bank and transfer over only what you need day to day or when currency rates are in your favour.
