We were living in Cardiff many years ago when SA played Wales. Wales was a lot better in the early nineties. No issue in pubs although wearing my green and gold and had numerous drinks bought for us when SA won. No animosity at all.
A couple of weeks later we went to stay up in the valleys for about 2 weeks. Walked to the pub for a drink and when he found out we were from SA the LL would not allow us to pay for any drinks. All on the house. At the time I was drinking Brains beer and OH Strongbow.
