Firstly let me start by saying yes I know manners are good and cost nothing etc..
HOWEVER, there are a couple of occasions where I think it is rude to respond to someone who has forgotten to say please with a sarcastic "PLEAAASSEEE" when you ask them to do something.
The first occasion is, you are asking them to do something mutually beneficial, that you shouldn't even have to be asking in the first place. Like can you set a load of washing on? PLEASE.... no I am busy doing the dishes why am I even having to ask you.
The second occasion is simple forgetfulness, "can you pass me the remote" PLEASE.....
It's so aggravating..... AIBU to feel slighted and irked by that?
