Retail annoyance

I go to Pottery Barn last night to grab a picture frame and on my way out I spot a vase that just might work as a Chuckit! and ball holder by the front door. (I'm currently working on revamping our entryway.) So I take the vase up to the counter. I'm in a bit of a hurry as the mall closes in 25 minutes and I still want to hit Sephora to grab night cream because, yes, I am old enough to require restorative night cream. I had a baby and sleep deprivation, much in the same way the camera adds 10 pounds, has added 10 years to my weathered and wrinkled face. The lady is pleasant in a noncommittal manner that suggests she isn't really concerned about providing a great customer service experience. And that's okay with me because I don't have the time. She notices a teeny tiny chip and then heads off into the store to see if she can locate another vase that isn't damaged. Truth be told, I didn't even see the chip and I wasn't bothered by it but since she had already left the counter I figured I'd go with it. No luck, the shelf is empty. Time to call the folks in back to see if there are additional vases. No luck, all out of stock. The woman returns to the counter and offers up a 10% discount. Fine. I'll take it. I just want to buy the thing so I can get it home and see if it will work in the space, which is what I'm explaining to the saleslady when she gets on the horn to call for a manager. Now we have to wait for the manager to bring up the key to unlock the register so my saleslady can complete the transaction. I'd be tapping my foot to showcase my irritability if I hadn't been raised better. The manager finally arrives and while this feels like it has taken nearly half an hour, only a few minutes have actually elapsed. The chip is reviewed by the manager who offers up a bigger discount. Fine. I'll take it. I just want to buy the thing so I can get it home and see if it will work in the space, which is what I'm explaining to the manager when she tells me that a discounted item becomes a final sale. And a final sale item cannot be returned. At this point, I am a bit exasperated. So I leave without a vase that I can use by my front door to hold Beauty the wonder dog's Chuckit! and tennis balls. I am vase-less. The search continues...
