Professional consistency is an issue across most service organisations.
Try calling 3 different police stations, ask them something and see how many different answers you get. Why? Because the chances are that you’re speaking to someone that his half way through their 7 months of training.
You then take their advice and run with it, not knowing that it may be sub-optimal, factually or legally incorrect.
It’s difficult to manage this and I can’t see ASA being immune from it. Rules are rules you think, but it’s not always that simple and no two employees are the same.
