Can I perform a border bounce by flying to Malaysia without an immigration stamp and return to Thailand on the same day?

Can I ask some questions here not related to visa itself, but about border-bounce?

These are what I want to know..

1. Can I check in the flight back to Bangkok (maybe DMK) at the international transit counter at KL, just after arriving from same airport?

2. Is that really no problem to enter the kingdom with non-B visa on same day of departure without Malaysian immigration stamp on your passport? TM.6 (arrival/departure card) would be with arrival flight number from KL.

3. Is there any other special condition to do this if is is possible?

If anyone had experience of this style of border-bounce, especially someone with any of multiple entry visa, would you share your story, please?

I'm going to fly out for one-day trip for my border-bounce with my Non-B multi to one of neighboring countries in this month.

Someone mentioned me to fly to KL, then I wouldn't need to go thru immigration at KL airport. Said once arrive KL just go to the transit counter to check-in to returning flight and come back. That means I will only exit and entry Thailand without going to any other country - on documents.

I flew to KL several times for my one-day border-bounce so far, but I always entered that country at KL through immigration (passport control), checked in to returning flight and went thru passport control again to exit from Malaysia.

I'm wondering if that really works or not.. If it works, of course it saves your time...

I might be just too much nervous.

Thank you for reading this through.
