The mishandling of a mistake on the cashiers part communicated very low regard for me as a customer. I was charged for three of something I purchased two of. I didn't have extra time to spare to go back and have them fix their error, but I'll be damned if I ever let a large business (whose workers continually communicate disrespect for the customer) have even 1 extra cent of my money. Time is money, money is time and time is the most precious commodity.
They have a "guarantee" that if they mischarge you for an item, they will make it up to you, but apparently not when they charge you for a whole extra item. When I asked about how their "guarantee" applied to me, they basically said it didn't. That it was only for when an item is charged "incorrectly". Now I'm not sure if the person working customer service really was that dense and could not see that if anything, charging a customer for a whole extra item is worse, or if it was pure disregard for my time and value as a customer. These incidences always communicate larger things. They add up. I have had my fill and won't be back.
