Worker wouldn't provide small piece of tape to seal box , had to buy $6 tape even though Amazon customers provide $12 billion dollars worth of profit.

Was told that's how they make their money for Amazon returns!

spelled out in UPS shareholder reports. UPS store managers probably don't read those and if they hear the numbers during those quarterly all hands meetings, they've zoned out before the earnings details are discussed.

But it's public information. It's not a factor for the store's P&L, it's just another shipping item on a commercial account. Just that the commercial account happens to be the whale. Amazon isn't a customer, they are a strategic partner with a special contract and regardless of which direction a package is going, the accounting isn't done "per package". It's a whole contract that amounts to 13.3 percent of UPS annual consolidated revenue (which is north of $84 billion).

So when you drop off an Amazon return, the UPS store manager isn't thinking "oh great, another cost we have to eat". If they think about it at all, it's the realization that without Amazon's business UPS would be in a lot of trouble -- $12 billion dollars worth of trouble.
