I got them all done but still left somewhat baffled by a few.
DOWN CLUE:
Freak piece of coal(3).
I've got NUB but I don't get the freak part. Maybe that's not the right answer.
ACROSS CLUE:
Hung about, wasting Tuesday? That's not acceptable(6).
I've got ABEYED. (the B is from NUB) I get the hung reference in the sense that something abeyed is in suspension but don't get the rest. Is it the right answer?
DOWN CLUE:
Wine merchant runs out after a month (7).
For this I have MOSELLE which is a wine and fits the pattern M - S - L - E but don't see how the rest of the clue works.
