The light system at the cash registers performance is a simple to understand process. When the light is on the register is open, when the light is off the register is closed. Simple and easy to understand.
Except at this Smith's. Apparently they want to complicate the process. There the the light can be off and the register is open, or the light can be off and the register is closed and lastly the light can be on and the register is open.
In order to tell if the light is off and the register is open the customer must approach the cashier a d ask, "is this register open". Dah
Due to an altercation over there interpretation, my money and I will be going elsewhere.
