Dick, as you have mentioned DSE, did you encourage your staff to abuse customers? I guess not as the customers would not return.
Now in a similar vein why do you persist in pouring abuse and ridicule on anyone who disagrees with you? le Pingouin, like others with whom you may disagree, is an expert in his job. He works with other experts who could have advanced your cause yet you choose to pour scorn on him.
Think how much easier your attempts at change may have been had you treated them as a resource and not done your best to put them off side. Again, despite your promise, your’re still applying your unpleasant ad hominem methods.
If DSE were still around, a manager with your behaviour would be up on harassment charges. Stick to the argument.
