In general really no, but I do see the point in not asking for permission for everything to get anything done. (I am german, here the saying is, anything not explicitely allowed is forbidden and there is no fun in this)

But I hate the stance when people do it, when it is clear that no permission will be given. To establish facts on the ground so to say.

(But there are exceptions where I think it is legit)
