Ooh, I'll play! I'm 40 years old. I write checks every month to pay my rent, which has to be delivered to their office either by snail mail or in person (no online payment option).
The last time I saw a dedicated fax machine was my retail job in 2008.
The last time I used a deposit slip was three years ago when I deposited a gallon bag of change in person with a bank teller.
How? Serious question. My bf is having this exact problem. Daily. It's bad.
