In all things I check my motives, did I seek out something with alcohol in it or did I eat/drink it thinking it was alcohol free?
Was you motive pure in eating that, or did you know and order it to have a teeny bit just to see what would happen?
I am sure I have eaten stuff at resteraunts that had alcohol in them, but it was not mentioned on the menu, nor did I order or eat it because I wanted to tempt fate. I avoid all foods and drinks I KNOW have alcohol in them.
That is just me, and like others have mentioned there are some recovered alcoholics that do on occasion use wine to cook & others that would never dream of it, I personally find other things that provide a similar flavor to cook with.
