I'll write a check if charged a fee not to write one. A few years back, I lived in an apartment building that added the 3% processing fee if you paid by credit card and 1% to pay electronically from your checking account. I'd write a check and just drop it off when walking through the lobby. (They eventually dropped the charge for one's checking account.)

The only check I routinely write now is to the gas company. They use Western Union as their payment processing vendor and WU charges $2.95. It's petty, but it's easy enough to write a check.
