Amazing this is now personally about fatsbat and his son and how they're dealing with it or not. Chucked in a little 'you're being racist' for what may be slightly ill-worded but probably doesn't have a shred of malicious intent to anyone.
Surely the real point here is, a chap was refused entry to a (shoddy) establishment for being in HM Forces. It is unacceptable and happens all too often. Leave the bloke alone, we should all be on his side or we should probably be reading another forum.
Fatsbat, your son is too worthy to drink in a Yates, clearly from your post he found a much better pub anyway. I totally agree with you that it's appalling, Mps want to assure us of how highly they value us, maybe a simple email to your MP could assuage your anger and prevent future young chaps being treated this way, better still maybe all yates and similar 'establishments' could be closed down saving us all from £1 for a double!!!!
