Ties,
I try to not be the uniform police, as I wear a US flag tie almost every day of the year. (If not Christmas or save the tatas month)
But my one pet peeve is have some self respect when checking into or out of a hotel (particularly international).
As in, if you normally wear you tie open and pulled down to your navel, maybe just those three minutes checking in or out of a hotel have some self respect and pull your tie up.
That being said,
I kind of like the idea of no ties at all.
Or some variations of that.
