The thing is is that a small percentage of people make up a huge portion of alcohol sales. Lots of people drink, but those who become alcoholic drink a disproportionate amount and the companies who profit know this. I worked in retail selling alcohol for years (my own worst alcoholic years, go figure) and it was the same group of people who came in each and every day to purchase alcohol. There were others that I only saw on the weekend, but those who got hooked were in every day, often more than once. It was really sad to see the state of some of them. I literally watched them fade away, they had the saddest eyes.
Best thing I ever did for myself was changing jobs. Oddly enough they contacted me just today to ask if I was ok being separated from the company to which I happily agreed. I haven't worked there in almost 4 years!
