What I should have said...

The scene:

In the Hostel reception a drunken man stumbles drunkenly, talking drunken nonsense in a drunken fashion to the really quite indifferent Hostel receptionist.  I enter stage left:

Me [to the receptionist]: Hi, can I have some sheets?
Drunk man: Please.
Me: Oh yeah, sorry I forgot, 'please'.

Exeunt drunken man.

Receptionist:  Here are your sheets.
Me: Thanks.

Exeunt me.

The drunken man has now deposited himself on the steps outside reception partly blocking my path.

What I should have said...

Drunken man:  She is a person, she's not your slave you know.
Me: Sorry?
Drunken man:  The receptionist.
Me:  Oh, you are referring to the fact I forgot to say please.  Allowing for the taciturn and really quite moody nature of the lady in question I will admit that not saying please was an oversight on my part and considering myself to have reasonable manners I would usually have said please without a second thought.  However, not saying please does not in anyway imply that I think she is a 'slave', any less of a person than me or any other, likely racial, inference your evidently drink addled mind may desire to conjure up.  I find my accidental lack of but one word substantially less offensive than your - I assume with some confidence - permanently drunken state.  Malaysia, if you hadn't noticed - but of course you hadn't -  is a predominantly Muslim nation and thus one which only tolerates alcohol and therefore likely finds a drunk such as yourself really quite abhorrent and only further proof of the dangers of drink.
Drunken man: [blank look]
Me:  Considering myself a generally polite man I see my slip in manners as no more indicative of a fall in standards than you should see one sober day as any sign of a halt of your slide into oblivion.


Alas, I just laughed and walked past him...
