Ah, I had the opposite experience. Asked by the airline staff, not asked by immigration.

Yes, you need both the airline to let you board, and the IO to let you through. But it's the airlines that ask you for proof of onward travel.

Especially if you have a bunch of COVID extensions in your passport. IOs are on the lookout for similar passports and people get refused re-entry. IO will let you in, outright refuse you, or try to find reasons to refuse you. Have the three things like Tod suggested. You'll have them if the IO asks for them. Good luck.

You're right next to a border, at around an hour of distance. Lucky you.

Yes, that's exactly how you can get the most days out of the METV. If you don't do that, it's essentially a double-entry. Can also extend for 30 days once back.

Try not to come back on the last day/s, since your transportation could easily break down, your plane could be cancelled, or many other things could happen, preventing you from re-entering that day.

From what country you entered from doesn't change anything regarding your extension. It's your nationality that is important.

If someone with a Non-Immigrant B visa (not an extension of stay), completed his contract and the employment was over, could he get a re-entry permit and come back in Thailand on the remaining portion of the Non-Immigrant B visa?

Regarding your second question, yes, you could come back in Thailand and get a visa exemption stamp (not a "tourist visa") when entering. If you enter on or after October 1st, you would get 45 days, and if you enter before that, 30 days. You can extend that for another 30 days for 1,900฿ at immigration in Thailand.

You could also apply for a Single-Entry Tourist visa at an embassy, which would give you 60 days and the possibility to extend another 30 days. However, you're allowed two VE stamps per calendar year by land, and since it's almost 2023, might as well use up your allowed VE stamps instead.

Could OP actually get a re-entry permit for their Non-Immigrant B visa, even though their employment ended before leaving?

Cambodia is one of the least best places to get a visa/do a border run. Poipet checkpoint is notorious for having immigration officers asking for bribes, and also having a higher chance of being denied entry.
