lowes Kobalt tools

I have one of Kobalt's small gravity feed spray guns. The screw on cap broke so I took the cup back to see if I could get a replacement. I told those idiots 3 or 4 times the gun was not in warranty. Two guys go behind the counter in customer service to get on a computer terminal. One guy asks me a question and since I couldn't hear him, I walked back behind the counter. They acted like I was trying to steal something. After about a minute, some heifer jumps all over my *** about being behind the counter. I told them to gimme my damned spray gun back and to go to Hell.
Came home and called the Corporate office in Wilkesboro, NC. Talked to a really nice young man who told me that they could have ordered the cap, no problem. He even had one put in the mail and shipped to me, no charge.
It all depends on the individual store. Although, if there was a Home Depot near, I wouldn't set foot in Lowe's.
BTW, I really like the Kobalt gun for small jobs.
