Thanks for playing! glad you enjoyed it.
They all have their pros and cons but I personally prefer the boots as they allow exactly enough time to reach the furthest shelf and get back as the next tape has finished rewinding.
The returns storage can be great for storing tapes when you are either being overrun by 2-3 tape customers and the queue is getting too long or for storing tapes that need to be returned furthest away as you can wait til you get a few 1 tape customers and clear the queue.
My favourite trick with the TVs is to return rewound tapes in the period between a customer leaving the counter and another joining, if it's one of the closer shelves then you free up an entire space without losing time AND if its far away and you have the storage then you can just put use the previous storage tactic and mitigate the downside.
