I sympathise with the tedium in seeing this same question asked every day.
The new system (for visa exempt countries) is to be ETA; ie one can use the electronic immigration gates so possibly negating the chance of encountering an immigration officer bad hair day. Perhaps the gates will be like slot machines where the ‘payout’ is adjusted by the immigration manager each week?
Also, I have no idea about bus timetables to Pattaya on Tuesdays.
