Me n my patient

It is really hard to have book fair here in Kuching... so, i won't miss any book fair..So, ths Sunday I went.
I bought 2 books thinking tht it is 70% off for the sign on the desk said so.. The next morning I notice, it was cut to 30% only...
I went there, asking for a redeem.. N the staff said "u r suppose to read the sticker first, it said 30%" with an annoying face..

Hello, what is wrong? is this how you communicate, treat your customer?
What the heck?? Perhaps this is one way for them to kill my patient.

So, here's d thing..

1-they blame the customer to move the books from different place..But nearly all books there has 30% sticker, and they arrange all the books as if 30% and 70% belongs together! In no definite order, 30% n 70% is mixed!!
I mean they rearrange the book so why not at the time they should put back the book to where they belong? N they are put in a desk written big : 70% for member, 60% for non member..

2-about the sticker, there not a single sign saying it, when I point "u should at least put a sign saying tht d price is according to sticker" n she said "it's a common sense!!" what the heck? come to think about it, if you have 2 different price, it's a normal ethic to pay the lowest one.. Especially it's a very old books.. At the same place, I can buy the latest book for 30% !! And, I know they just a bunch of lazy people who hate to do troublesome work..[sigh]

3-what I ask is simple, I don't mind paying for 30% , but all I ask is to be treated as a customer.. Why don't start with "I m sorry for this misunderstanding, miss....."
here, let me emphasize the magic word... SORRY...
