I understand what you originally said and my reply to what you said, "I regularly wear dressier shorts (ie no gym or, for me, even plain khaki shorts) and a collared shirt to all restaurants and I’ve never felt out of place or underdressed. I’ve seen people wearing mostly gym-level attire and they look out of place but still allowed".
Hench my comment, "shorts are shorts" no matter your interpretation of what shorts are or what types should be allowed in the MDR in the evening.
I personally don't care what others wear in the MDR in the evening. Above my pay grade.
"Geesh". 😂
