Aye, getting interrupted is enough to make me
EXPLODE. I get like that when watching an informative TV broadcast too - my brain is in "information receptive" mode and getting it slapped out by someone asking Q's is not enjoyable.
Someone here (I think it was Neilmarr) mentioned about wearing a specific hat that indicated "If you disturb me I will not like you" or similar.
Sure, if it's an emergency ( "The house is on fire!" ) then I suppose being interrupted is acceptable, anything other than that should be punished
