The real questions are :
What do you mean by the statement my passport is running out of days?
Do you mean you're current stamp is running out?
OR
Do you mean your passport is expiring soon?
Another question is WHERE are you in thailand?
If you're in Bangkok there are border bounce services that take you to the borders in Lao and back SWD Transport is one (www.thaivisaservice.com)
If you have an extensive entry/stay history you are unlikely to bounce yourself out/back at the Nong Khai border without either being told to stay IN Lao 2 days or so OR being told you can leave but have to fly back in <- which again, with an extensive entry/stay history (especially if it's free stamp visa exempt entry) can come with it's own set of problems
We used to regularly see bar closures enforced for infringements of one sort or another. Your comment made me realize I had not heard of such an event for a good while. Now it is simply bars failing financially.
