Have you ever gone into a convenience store, and had nothing but problems at checkout? The other day I went into 7-Eleven, and the POS systems were all having an issue. The keyboards weren’t working, and the scanners weren’t operating correct either.
Every business that has a register needs to make sure that it works 100% at all times. I don’t think that it looks to professional for a register to be inoperable at times that it is needed.
I have seen some real elaborate systems in my time, and the ones at most of the convenience store just go to tell me that they must be making some good money to be able to afford them.
