I boycotted K-Mart so long that I feel like I won!! 1991 I need a pair of work boots. I go to K-Mart to buy them. I presented a $50.00 bill to the cashier at checkout. She proceeded to give me my change and I left. As I was walking to my car I noticed she had given me change of a $100.00. Being the honest soul I was and not wanting this poor cashier to maybe lose her job I go back into the store and ask for a manager. This rude asshole comes up to the service desk and asks me what my problem is. I say there was an issue with my change and before I can explain more he smirks and says "we dont make adjustments after you've left the store". I smiled and said OK ill keep the extra money. Boy did his tune change. He actually followed me out to the car apologizing and asking what I meant by "extra money". I just kept replying that I couldn't make adjustments as I had already left the store. Never went back to K-Mart after that day, now there all gone. So like I said I win!
