Certainly makes a good case for having the now long obselete click-clack imprinters and the paper vouchers as a fallback for these types of situations.
Whilst I was at our local Coles on 23.12.2019, their EFTPOS was down so they were getting customers to sign the bottom of the dockets, but when I went to another nearby Coles, everything was normal.
When I lookesd at the entries on my CBA MasterCard the next day, the signed transaction had already been completed whilst the EFTPOS one was stiil pending, as usual.
