They Don't Know Maths!!

OK every item is bought from the supplier at the cost price which is about 20-40% off the retail price. Then when these items have discounts, during fairs etc, their price go down another 10-20%. Example, an item is RM20.00, at cost price (40%) its RM12.00, and with discount (10%) its RM10.00 with the discount amount counted from the retail price. Right? Another item is also RM20.00 at retail price, cost price at RM12.00, and with the discount 10% counted from the COST PRICE, the price becomes RM10.80. There is a difference right? Imagine when there are hundreds n thousands of that item. The difference isn't going to be "aiya 80cents oni ma!!"

I've been trying to explain that the way they key in (and asking me to key in) these datas are wrong. And that colleague of mine (Ms A) just don't understand. She just said that it doesn't matter as long as you just enter the amount at "Sales Adjustment" to balance them, following the total in the invoice which she already made (you'll be shocked at the silly mistakes she made). I just need to let it off somewhere and i'm doing it here. Anyway, so her logic is this-key in all data, if its not the same with the one in invoice, just add/minus accordingly to match them at the Sales Adjustment. I've been adding/minus the total which don't match because she's too lazy to check the openings and balances like she should. Instead she just copy whatever the supervisors feed her. Argh. Well, since I'm leaving this company which have a sucky system, i shouldn't care!

The arrangement for transports for deliveries and returns have another stupid long process. My other colleague which started work with me at the same time (Ms.B) had to copy 1 thing to 3 different books to keep a record of what going in and out. Example, returns for 1 book, deliveries for 1 book, transport company name 1 book, transport by our driver 1 book, and another 1 for the number of cartons/offer bins. They can't just use a log book to record them all. Don't know why. OR!! just use the computer dumbass. Amazingly, the same colleague which her wise logic (Ms A) , suggested to record in another book for every in and out with outlets. and the manager agrees with her saying its a great idea. Poor Ms B.... as if the other books don't already have them. Imagine when there's 5 deliveries n 5 returns, she gt copy each of them in more than 3 books..... -_- what a waste of time...

Im shortening my life working here, trying to point out their mistakes by acting the dumb one, like, "what's this? i don't know how to do it, it can't be balanced..." rather than, "wei.. why this thing all wrong wan? how u do geh... check properly la... see ur report i oso vomit blood... think i very free correct for u meh? u know how to do ur work anot? work so long already still dono how to do properly? other people few weeks also seng mok already... what is that inside ur head? nothing? i feel this job no suit u la! change other job ba."
