We lost so many customers because our store was too hot in the summer and too cold in the winter. Dimming the lights didn't help either. We used to joke that the lights were dimmed so customers couldn't see how dingy the store looked, and that the one-touch plan to push all stockroom merchandise to the floor was so that they could turn off all the lights in receiving. You felt like you were working in a cave.
I don't blame the QMTs as they were only doing their job, but man, those energy cuts really, really hurt our business.
