To the return clerk at Home Depot:

I am returning/exchanging my item because it is defective. I bought the drill bits because I want to drill through tile without damaging the tile. For you to ask me if I "didn’t have a file at home" so that I could file off the burr on the side of the brand new drill bit was an insult. I purchased a product from your store to fix something. It is not reasonable that I should have to fix the new product before I can use it to fix something else.  I hope my snort of incredulous laughter as I told you NO was not too terribly offensive.

From:
the snippy lady with the ansty two year old who waitied in line for over 20 minutes to be asked to fix her newly purchased merchandise.

btw:  the exchanged drill bits are excellent in quality and I DO appreciate you not making me wait in line a second time to complete the transaction.
