A fair point douglas - the constant coughing has always been a nuisance in televised snooker.
As for the people who shout - I think it's just the atmosphere and adrenaline that makes people act without thinking - that's an explanation, it's not an excuse!
For a while after Covid there was almost no coughing in theatres - which was lovely - as people were afraid of being chucked out. Now it’s back to a free for all.
Also chuck out the people whose phones go off. One warning, then the next one leaves.
