Deplorable service from an individual

I have been a Brights customer for many years, which is not really important,if I went into their store now, having never been there, I would expect good service. I usually do my shopping at the Uitzicht store which is closest to me, I used to use the Stickland store,but have moved.Anyhow I have been looking for 8mm staples for my staple gun, which I use a lot, (I restore furniture). Last December went in , they didn't have stock, sales guy says they have ordered but supplier out of stock or some reason.Every 2 weeks or so I would pop in, same story,or excuse.This kept on into this year,I would see the same guy,same story.Yesterday, the 12th February, went in,again same story, went to the the branch manageress, told my story, she clicked away at her computer and ''yes they have been on order since November or December, but no joy, She phoned ,I presume the supplier,and said they would be in stock this coming Friday. At least she made an effort to try and source these staples, which I am desperate for and use constantly, I can't do my work without them. Today I happened to be in Stickland to visit another supplier for some hinges and while in the area decided to pop into Brights to see if they might on the off chance have my 8mm staples, lo and behold, all sizes,6mm,8mm.10mm,12mm. lots of them,couldn't believe it. So how come Stickland have stock and Uitzicht don't. How come the sales guy couldn't be more service orientated,maybe make an effort, phone the supplier, click on his computer and see if the other branches had stock, maybe just try and be more helpful with a customer that is obviously in need of the staples. In my opinion with what I experienced with him over these last months,knowing that possibly Stickland had stock was that his attitude was one of ''didn't give a damn, I get my monthly salary,so what else is important'' Customer service, try it.
