Yes, because I can always come back later and politely ask the Manager to review the CCTV to confirm the misunderstanding. Yes, it sucks to pay extra, but know your area and practice situational awareness. You will lose trying to get all "tough guy" here in this country. Better yet, get a Thai person who can translate to help you mitigate the situation with security. From the CCTV, it appears the unfortunate guy who got his head kicked, was drunk and aggressive. Not a smart move.
