Fire an outside company?

I'm adding in an extra post today. Because one of the blogs I read (once I figure out how to post links, I'll get her link up here) reminded me.

Last weekend we had a computer problem. Nothing new. Since I've worked there we have had nothing but problems on the weekends. I've learned how to handle things accordingly.

This time it was the nurses computer. She's new too and at her wits end for the day (it was 7 am and it was already shaping up to be a long day for the poor woman). So she's trying to fix it, and I'm working my best to fix it for her. Neither of us are succeeding. I go out to the waiting room to update the patients and check the rest in. Some wise ass chimes in and tells me "you need to fire your IT people." Really? I tell the patient "they are an outside company. We really have no control over what happens with their systems." "We pay all this money can't you afford a better system?" Ummmm... "Corporate chose this system. We can't do much about it" (not to mention does the patient think that methadone is free and the clinic just blows their money?). "Yea well you need to fire them!" Again "its an outside company we can't do that." "Well why?" Thankfully her computer was up and running again and he got buzzed back...
