It depends on the store. We rarely had a night when we DIDN'T have a trailer - most nights we had duals. But that was in a AAA+ volume store.I never heard of a trunk coming on Saturday/Sunday night after Christmas.
It must be for Reset.
The stores close at 10 pm! That's a first.
I worked New years over night. We got holiday pay witch is based on the average hours you work. So in the end you get an additional days pay.
