As far as I'm concerned checks are simple and low stress. If you don't prefer them that's as valid an opinion as mine, but why is the option of paying by check seen as so awful? For instance, elsewhere in this discussion (emphasis my own): "no landlords I talked to took cheques, thankfully." What's so great at other people being denied their preference??
