I went along to the New Sydney Hotel (a reasonably knockabout Irish pub) see my workmate's band The Fops play on Friday night, and was not let in, on account of my footwear - clean walking boots. The guy also mentioned my shorts. In my experience you can never debate with people in his position so I went home.
The reason I didn't get changed and go back is that I think its ridiculous to be excluded from a pub for wearing shorts and boots. I'll be giving this place a wide berth in future. If I'm going to go to the trouble of wearing flash shoes (which I don't very often) it will be for a more significant occasion than going to the pub.
