Flying J, Berkshire OH

2/25 I stopped and ate at the Flying J on I 71 just north of 270 in Ohio. Aside from the mediocre service, I didn't notice anything out of the ordinary. This morning when I woke up, all the staff of the restaurant was present, but the restaurant was closed with signs on the door apologizing. I went to the counter to make a purchase and heard the manager telling maintence to get the place cleaned up because they would have to be inspected before the restaurant reopened, and that the fire inspector guy would be there.

Anyone know what happened?
