Q:   Don't give me that, you snotty-faced heap of parrot droppings!
M:   What?
Q:   Shut your festering gob, you tit! Your type really makes me puke, you vacuous, coffee-nosed, maloderous, pervert!!!
M:   Look, I CAME HERE FOR AN ARGUMENT, I'm not going to just stand...!!
Q:   OH, oh I'm sorry, but this is abuse.
M:   Oh, I see, well, that explains it.
Q:   Ah yes, you want room 12A, Just along the corridor.
M:   Oh, Thank you very much. Sorry.
Q:   Not at all.
M:   Thank You.
