Ive never bought into the myth that how you look is completely irrelevant in the world of beer bars,girls and bar fines.
If you are young and good looking sitting in a bar beside an old fat guy the young guy will leave with the better looking girl. Its a fact of life no matter where you are in the world. Ive sat in my mates bar in second road and watched girls knock back ugly badly dressed guys who were practically throwing money at them.
If you make a bit of effort with your appearance they do appreciate it. The girls will approach you first and be a lot less grudging when it comes to the end deal.
Sure the fat guy in the vest may get the girl sometimes but he will always be last choice and he will have to live with the thought that she hates him.
