Lucky you weren't thrown in jail.
Why would he be thrown in jail? It's not as if the RTP are upholding a higher standard here is it? We are talking about the noxious collective that is the Immigration Police and not some squeaky clean, anti-graft body.
It's like a forum member last year who had his previous extensions acquired via a Pattaya agent for the convenience and not due to lack of funds. He decided he had the time to do it properly at Chaengwattana. He got his passport with a 'bad' extension chucked back in his face by a ranting, sanctimonious Chaengwattana paper shuffler who, after he got off his high horse, offered to correct his ill-gotten paperwork for only fifteen thousand baht.
Shills. The lot of 'em.
