Harbor Freight Knoxville TN nice way to treat a long time customer Knoxville Tennessee

I have been a long time customer at Harbor Freight knoxville TN on Broadway, i have never been treated so rudely by a clerk and the manager. i made my purchases and on the reciept i noticed i was charged regular price and took it to the clerk, and he rudely said i did not show my card, i told him i never had to show a card to get the advertised discount price he walked away and yelled see it says on the sale marker you have to show a card, i am a disabled army veteran in my 50's and my eyes aren't as good as they use to be, and know he yelled at me in front of alot of other people, i was at that time upset to say the least. i told him to refund the sale items i will repurchase at the advertised sale price, the manager came up and said the computer was not working so i had to come back, i told her the computer worked to ring it up, why do i have to come back, she also started to yell and act very rude, i told her i had shopped there for years and never showed a card to get advertised sale prices, she repeated come back later very rudely in front of alot of other customers, i reacted badly and told her what she could do, use your imagination. i said i would never shop there again, she said good, don't come back. my friends in the auto club, antique car club and my family will not be back kim. i ask her to write her name down she pointed to her name tag and said remember it. i do remember and will tell everyone who will listen to remember it Kim manager of Harbor Freight in knoxville Tennessee
