Customers.

You know what I fucking hate? Customers who come in, don't know what they want, can't describe what they want, but absolutely insist that they bought it from you 'months ago', and give you shit when you (1) don't have a clue what they're saying and (2) say that they must be mistaken because we don't sell that.

Yeah. I just had some Indon dude have a go at me because he insisted that we have whatever he was looking for (I still have no bloody idea), and that he bought it from us the last time. Whenever that bloody was.

Edit: As it turns out, he confused us with another store. Didn't bloody apologise for giving me shit either. Oh, and he's a motherfucking pastor. Well done.
