I gave a lot of thought to this conversation.
However anyone feels about specific rules of attire/conduct or even the wording involved, I have found this:
Companies who have a "culture" of teamwork, positive first impressions, and positive internal communication are more easily managed, have employees who stay longer, and have less internal strife. Its not so much the "letter of rules" as it is the atmosphere of mutual respect for each other, and for the customer, that makes them effective.
This is so very much better than the internal memo from a large company I had kept here for awhile that said, in part that "asking customers out on dates, or their children was no longer permissible" and that "have sexual relations with customers on the job would now be grounds for immediate dismissal"
If you have to spell that out, there is an extraordinary bad company culture present, to say the least.
