I enjoyed this take on the theme! It was fun trying to find the most efficient system to handle customers, I usually waited for customers in front of the counter so I wouldn't have to walk around it.
The TV upgrades are a good idea, but aren't that helpful since you lose more time taking tapes to the shelf rather than rewinding them. Other upgrades like a basket that lets you carry multiple tapes, or something to increase your move speed, would be more beneficial.
