Even if it was "just a gift" if that is the excuse for such things, then gifts can be refused, you do NOT have to accept that fancy rolex or $17000 iwatch.
In fact I reckon it would be immodest to accept it or even allow anyone to believe that you might accept it. You'd go out of your way to prevent anyone from imagining it was a suitable gift to give in the 1st place thus avoiding the possible situation and awkwardness all round if someone was to offer it.
if these are gifts then the ones accepting them have no shame and no ethics. If they are bought with their own money then they have no shame and no ethics. If they are rewards from corporate deals then they have no shame and no ethics.
There is no set of circumstances in which it is OK for a GB member to wear such items without looking like a complete sham.
So keep it up you gormless 7, you may wake a few more up that way.
