Quoted from chad:
Went to the main UPS to send out a package and evidently they stopped taking cash in in September 2017. I asked why and he thought because they are at the airport but wasn't sure.
I personally do not want to go down the cashless road.....
I'm not seeing any headlines or other forum posts about this. I would think it would be big news if it was widespread.
Maybe some sort of misunderstanding? Maybe the cash drawer wasn't functioning that day?
