A dollar? Really?

Got a text today from Aspen Dental regarding a balance on my account, so I called. 'We were just trying to reach you about the balance left after your insurance so you won't go into collections,' Matt said. 'Oh,' I said, 'I haven't gotten a bill or anything. How much of a balance is it?' '$1.00' he says. '$1.00. A dollar?' 'Yes. Did you want to pay it over the phone or come in to pay on it?' I did pay with my flexible spending card, but seriously, you never send me a bill for the amount and then talk collections over a dollar? Matt could not see the absurdity of it, I guess. He just went on as if it were $100 rather than one. Mind you, I have the Dental Managed Organisation (DMO) insurance, where you pay half of what people who have the Dental Preferred Provider network have (think PPO, but dental), so that's the only practice in my network, basically. But still, really? Weird. Makes me want to change come October. The only consolation is they probably paid more in credit card fees than they collected from me. :)
