On Saturday afternoon the software for the marijuana dispensary updated. The software updates were going to take about an hour, but it took way less time than that for problems to come up. We were closed for the hour that the marijuana dispensary software was updated. As soon as the system was back online, we opened up the doors and started selling items. It’s never good to be closed on a Saturday even for an hour and we were probably closed for 2 hours total. The software company technician promised me that the system would seamlessly integrate and there would be no problems. That was not at all how it seemed to me. After we turned back on the lights and opened up the doors, we had a lobby full of people. I was working on one of the registers and tried to use my skating machine. I tried to scan the barcode on the back of the item several times. When no items showed on my screen and no items were prompted, I decided to look for the marijuana dispensary item by typing in the individual name. That didn’t work either. When I asked for the marijuana dispensary software to show me all of the items that were available as edibles, the software said zero items found. There was a glitch in the software and I immediately told my manager before we let any other people inside of the building. The people who installed the software had to come back and fix it and they needed to do it quickly.
