I park - if there is a space right in front of the spa. For those who knows eSpa, I park right at their entrance and walk in. No hat, no sunglasses, nothing.
Do I care if my business clients see me. No. I provide a service to them. It is a very good service. If they decide to take their business elsewhere because of their Morals then go. I have no time for those who judge other's Morals based on their own.
On the other Hand - my SO - now that is a completely different story.
