of course even 1 day... where would you like the line to be drawn after you have not adhered to the Immigration rules? 10 days? maybe you think 25 days?
100%... many people give to advice that it is 'ok' to overstay a few days.. just pay the 500thb fine per day when leaving... they fail to mention what will happen 'if' they are pulled up by the BiB... sounds like this guy is going to deserve his nice red stamp.
