OLL: Not sure what type of vinegar you had, but sounds like you did not intentionally order the dressing, thinking it had alcohol. In addition, you did not continue to eat the salad since there was a distinct taste. I've eaten salads with vinegar and oil type dressings this past year. It was never my intent to consume alcohol and sounds the same for you. IMO, you are doing so well with your recovery. If having certain types of salad dressings concern you, next time just order whatever dressing you choose on the side. That way you can still enjoy the salad, even if the dressing isn't quite right. Go easy on yourself, you are doing great!
