### Clue: Hurry up, mum – man's removing hot towel (4,2,6)
### Answer: MAKE IT SNAPPY 
 ### Explanation: MA(*mum*) KEIT[h]'S(*man's*, without,*removing h*[*ot*]) NAPPY(*towel*).  A nappy, short for napkin in the diaper sense, is sometimes made of towelling (nowadays, mostly synthetic materials used instead);  whilst a table napkin is likely to be a small towel, I'm not sure that "nappy" can be used for the latter, not least, so as not to confuse the waiter when you ask for one!
