I'll admit I was taking a risk, but I found it somewhat gratifying to go into my 'main' beer stop just to grab a fountain drink and some chips last month. All of them use to know me as the scruffy looking guy always grabbing a twelve pack (at the least), not saying much, pay and leave. He asked "No beer for you?" and I told him I had to change my diet, with a smile and we talked for a little while.
I've gone in there and most of my other old beer stores a few times in the last two months and most of them seem impressed and thankful I'm not dead.
Good Luck with your sobriety and do your best to be grateful for it. Do it for yourself, not for others.
