Yet these restaurants always have a waiting list....and there are many who like and prefer them.
It is perfectly fine to go to the gym in a suit and tie and workout. But people do not usually dress that way there so you will be stared at.....maybe hear a few laughs....and would probably feel uncomfortable. Do you feel that the gym patrons, are justified in their actions? do you agree with them or agree that you would look harder at one you see working out in the suit?
Well there are those who expect a certain attire in church buildings. are they justified as much as the gym patrons? Would the one working out feel lead to never enter a gym again, as you ascribe to the church goer made to feel uncomfortable in the church?
Just like with the restaurants, you can find a church that will match whatever dress code you desire.....and not one of them is better than the other because of it. Just personal preferences that should be respected and adhered to....
