Oil leak after oil change?

So basically I went to jiffy lube and got an oil change, car started and continued to leave oil. Not just drops either, puddles. I went back and basically they told me my gasket is busted but they are not liable. I understand this as I has an old car (2002 honda civic lx) with previous leaks but the last time I had it changed before this time in March it did not leak any oil, of course jiffy lube did not do that oil change. So I'm wondering what could this be? Is there anything I should specifically look for?
