I did not. Might try that next time they ask.

Correct. You don’t have to deal with the guys outside. Go at the window and they will give you what you need.

No. I did not use their service. It was for the guys in the office who was issuing the visa.

Back in October 2022 I did cross and back in one day with E-Visa. They did ask me the 100THB for administration purpose. I did have to fill the arrival form. Did not save much time really. Personally, the only good thing about the E-Visa is you don't have the full page sticker. On another note. Yesterday I did Bounce with no E-Visa form Nong Kai and back. Went flawlessly. 35THB for bus across the bridge. 1700THB for the visa. 30THB for the bus back across the bridge to Thailand. No question asked. About one hour total from Thai Border Out to Thai Border In. No ATK Test or Vaccine proof needed.

When you got vaccinated, they probably gave you a certificate and all that. Just show this at the border.

No. It needs to be done in a clinic and get certified. Bangkok hospital will do it, if there is one near you. Only need to walk in with your passport and ask for ATK. It will cost you around 170THB. Done in about 30 minutes, if not too busy.

I crossed to Vientiane via Friendship Bridge yesterday and they did ask me for proof of Vaccine or ATK (Antigen Test)
