Can you get two extensions in a row at Bangkok immigration?

Can you still get a 15 day reentry by going to Cambodia

Will the immigration police come looking for me if I overstay by 8 days?

People can get many extensions in a row but for a specific case it would depend on what visa or permission to stay you wanted to extend and the purpose for the extension, more info needed.

If you enter Cambodia by land and return to Thailand straight away you would be given a 15 day visa exempt entry if your nationality entitled you to it , again more info needed to be sure.

If you overstay any length of time the 'computers' do not automatically issue all points bulletins to apprehend you. But if, for any reason, you are stopped by the police you may have problems.
