The only place I still write checks for is our on-campus cafe, to reload my badge with funds. For the longest time, you could only do checks or cash to load your badge. They then installed an ATM machine, but it charges something like $3 per withdrawal. They recently added the ability to reload your card online. There's something like a $5 fee per reload.
I still use my checkbook.
I still use checks for tithing at church. Almost everything else is credit cards now.
When I started at my current job the cafe was cash only (and they had an ATM that didn't charge a fee so not that big a deal) but they have switched to taking cards so its an oddity that I have cash right now.
